DETAILED DESCRIPTION

[0009] The present application relates to processing verbal content detected via a microphone and identifying an audio script that can specify sound effects that can be played along or in time with the verbal content. For example, when a user is reading a book, an audio script can include or specify sound effects or background music selected to accompany the user's reading experience. When a user is singing a song acapella, an audio script can be music that is associated with the melody and/or lyrics of the song.

[0010] Embodiments of the present disclosure can allow a user to hail or retrieve an audio script by way of a verbal command. In some examples, a device equipped with a microphone can facilitate detection of a book or a song that is being verbalized by a user and initiate playback of an appropriate audio script that facilitates the playback of sound effects at the appropriate time to enhance a user experience. In some embodiments, upon detecting that a particular story or song is being verbalized, the system can query the user to determine if the user would like for the system to accompany the story or song with associated sound effects.

[0011] With these embodiments, users can issue a verbal command, such as, "play a soundtrack for" a book or a song, where the user verbalizes the book title or a song title, and then an audio script is played. Additionally, playback of the audio script can be synchronized with the user's verbalizing of the book text or song lyrics. Synchronization can be accomplished through an audio script defining triggering events, such as cue words, word groupings, or phrases for various sound effects. Triggering events can also define when certain sound effects should be terminated.

[0012] Turning now to FIG. 1 , shown is an example scenario 100 in accordance with various embodiments. In the example scenario 100, a user is reading the text of a book in the presence a voice interface device 102. The voice interface device 102 can be equipped with one or more microphones so that the user's voice can be captured and analyzed by the voice interface device 102 or computing devices that are in communication with the voice interface device 102. While reading a book, the user verbalizes a particular portion of the book in the form of verbal content 106a: "And then an ominous storm rolled in... "

[0013] The voice interface device 102 can detect a triggering event, such as a cue word, or group of words, in the verbal content 106a that are associated with a sound effect 109 or track of an audio script file that corresponds to the book being read by the user. Once the one or more cue words have been verbalized and detected by the voice interface device 102, the voice interface device 102 initiates playback of the sound effect 109. In some cases, a sound effect 109 might include a longer or repeating sound effect or track, such as background music or background noise. Accordingly, such a sound effect can play continuously upon detection of the cue word or phrase until a subsequent termination cue word or phrase is detected. Therefore, upon detection of the termination cue words verbalized by a user as verbal content 106b, the voice interface device 102 can also terminate playback of the sound effect 109 and await verbalization of the next cue words that are defined by the audio script, if there are any. In the following discussion, a general description of the system and its components is provided, followed by a discussion of the operation of the same.

[0014] With reference to FIG. 2, shown is a networked environment 200 according to various embodiments. The networked environment 200 includes a voice interface device 102 and a computing environment 203 in data communication via a network 209. The network 209 includes, for example, the Internet, intranets, extranets, wide area networks (WANs), local area networks (LANs), wired networks, wireless networks, or other suitable networks, etc., cable networks, satellite networks, or any combination of two or more such networks.

[0015] The computing environment 203 can comprise, for example, a server computer or any other system providing computing capability. Alternatively, the computing environment 203 can employ a plurality of computing devices that can be arranged, for example, in one or more server banks, computer banks, or other arrangements. Such computing devices can be located in a single installation or may be distributed among many different geographical locations. For example, the computing environment 203 can include a plurality of computing devices that together can comprise a hosted computing resource, a grid computing resource, and/or any other distributed computing arrangement. In some cases, the computing environment 203 can correspond to an elastic computing resource where the allotted capacity of processing, network, storage, or other computing-related resources may vary over time.

[0016] Various applications and/or other functionality can be executed in the computing environment 203. Also, various data is stored in a data store 212 that is accessible to the computing environment 203. The data store 212 can be representative of a plurality of data stores 212. The data stored in the data store 212, for example, is associated with the operation of the various applications and/or functional entities described below.

[0017] The components executed on the computing environment 203, for example, include a query response service 218, and other applications, services, processes, systems, engines, or functionality not discussed in detail herein. The query response service 218 is executed to receive data encoding a verbal content 106 from a voice interface device 102, process the verbal content 106, and then play sound effects in the form of an audio script. As will be discussed, the query response service 218 can return a response for presentation by the voice interface device 102 to obtain additional a user selection of an audio script if more than one audio script is identified that might correspond to the user's initial selection.

[0018] The computing environment 203 can also execute one or more applications or services that facilitate purchase, rental, borrowing, download, streaming or other forms of acquiring content such as books or songs. In one example, a user can purchase a book, and the book can be associated with an account of the user in an electronic marketplace. As another example, a user might subscribe to a music service or other membership group that provides the user with access to songs, books, or other forms of content.

[0019] The data stored in the data store 212 includes, for example, a content library 227, user account data 229, and potentially other data. The content library 227 can include information about various types of content that have a textual component, such as books, which are associated with text, or songs, with are associated with song lyrics. For a particular piece of content in the content library 227, a content type 231 can identify whether the content is a book, song, or another type of content that has textual component that is also associated with an audio script. A piece of content can also be associated with one or more content titles 233. In some scenarios, a piece of content might be associated with more than one content title 233 to facilitate disambiguation when a user might verbalize a colloquial or commonly known title of a piece of content that might be different from an official or authoritative title of the content. For example, a user might speak "Harry Potter Book 1 ," rather than "Harry Potter and the Sorcerer's Stone." In this scenario, both titles can be associated with a piece of content as a content title 233. As another example, a particular song title might be associated with content from multiple artists. Accordingly, the content title 233 can also include artist information so that the correct content can be identified by the query response service 218.

[0020] In some examples, a piece of content can be associated with the textual content 235, which can be the full text of a piece of content. For example, the textual content 235 can include the full text of a book or the full lyrics of a song. It is noted that the full textual content 235 is not required in order to facilitate playback of an audio script according to embodiments of the disclosure.

[0021] The audio script 237 defines the sound effects that are associated with a piece of content as well as when a particular sound effect should be played. In other words, the audio script 237 includes the audio content in the form of sound effects, background music, or other audio content. The audio script 237 associates sound effects with a particular portion of a piece of content. In one example, the audio script 237 can define one or more triggering events that are linked to a sound effect. In some examples, the audio script 237 can also divide a piece of content into various scenes, chapters or verses so that the same or similar cue words can be linked to potentially varying sound effects in different portions of the content. In one example, triggering events can be one or more cue words, word phrases or other verbalizations that can be detected. For example, particular cue words in the first chapter of a book can be linked with a first sound effect by the audio script 237, but the same cue words in the second chapter of the book can be linked with a completely different sound effect.

[0022] The additional data 239 can identify whether a piece of content is associated with promotional information or rewards. In some scenarios, a reward or promotion can be provided upon initiating playback of an audio script 237 or upon completion of an audio script 237. For example, a retailer or an electronic marketplace can offer an incentive for a user to initiate or complete playback of a particular audio script 237. Such a reward can take the form of a gift card, promotional credit, a free or discounted book or song, or other reward that be associated with a particular user account. The reward or incentive, in one example, can correspond to any item offered for purchase, download, rental, or other form of consumption.

[0023] As another example of additional data 239, a particular brand of potato chips may be mentioned in a book or song. The additional data 239 may be used to promote products that are related to or mentioned within content. These promotions can be provide to a user in the form of ad placements when the user is browsing a website, using an app on a device, or verbalized through the voice interface device 102.

[0024] The user account data 229 includes various data about users of the computing environment 203. The user account data 229 can include acquired content 243, history 245, configuration settings 247, and/or other data. The acquired content 243 describes content in the content library 227 to which a user has access. For example, a user may have borrowed, rented or purchased a particular song or book that is associated with an audio script 237. Accordingly, the acquired content 243 can identify audio scripts 237 that a user is entitled to access via the voice interface device 102. In some cases, the acquired content 243 can identify books or songs to which a user is entitled to access, and a lookup table can cross-reference the books or songs with corresponding audio scripts 237. In one scenario, a user might have a subscription that provides access to all or some of the content in the content library 227. For example, a user might have a subscription or entitlement that allows the user to access a swath of audio scripts 237 from the content library 227. Such a subscription may be limited in some way (e.g., number of titles, number of bytes, quality level, time of day, etc.) or unlimited. [0025] The history 245 can include various data describing behavior of a user. Such data may include a purchase history, a browsing history, transaction history, a consumption history, explicitly configured reading, listening or viewing preferences, and/or other data. As understood herein, a "user" may refer to one or more people capable of using a given user account. For example, a user may include one or more family members, roommates, etc. In various embodiments, the extrinsic data may be presented based at least in part on general history of a user account, history of a user account that is attributable to a specific person, and/or history of one or more related user accounts.

[0026] The configuration settings 247 can include various parameters that control the operation of the query response service 218 and the voice interface device 102. For example, the configuration settings 247 can encompass profiles of a user's voice, dialect, accent, or other characteristics of the user's speech or language to aid in recognition of the user's speech. These characteristics can also encompass aspects of the speech of multiple users in a household that may share usage of the voice interface device 102.

[0027] The voice interface device 102 is representative of a client device that can be coupled to the network 209 and in communication with the computing environment 203. The voice interface device 102 can include, for example, a processor-based system such as a computer system. Such a computer system may be embodied in the form of a special purpose appliance that is intended to receive verbal commands and play sounds through one or more speakers, a smart television, a desktop computer, a laptop computer, personal digital assistants, cellular telephones, smartphones, set-top boxes, music players, web pads, tablet computer systems, game consoles, electronic book readers, or other devices. The voice interface device 102 can be employed to receive voice commands or verbal content 106 from users and respond through a synthesized speech interface. The voice interface device 102 can also play sound effects, music, or other sounds through one or more speakers. Although described as a single device, in some examples, a first device can receive or capture verbal content 106 from users, and one or more other devices can facilitate playback sound effects or responses generated by a speech synthesizer.

[0028] The voice interface device 102 may include one or more microphones 285 and one or more audio devices 286. The microphones 285 may be optimized to pick up verbal commands or verbal content from users who, for example, might be in the same room as the voice interface device 102. In receiving and processing audio from the microphones 285, the voice interface device 102 may be configured to null and ignore audio from other sources, such as music sources, video sources, or other ambient sounds, that are present in the environment in which the voice interface device 102 is installed. Thus, the voice interface device 102 is capable of discerning verbal commands from users even while other ambient noises and sounds are simultaneously picked up by the microphones 285. The audio device 286 is configured to generate audio to be heard by a user. For instance, the audio device 286 may include an integrated speaker, a line-out interface, a headphone or earphone interface, a BLUETOOTH interface, etc.

[0029] The speech synthesizer 288 can be executed to generate audio corresponding to synthesized speech for textual inputs. The speech synthesizer 288 can support a variety of voices and languages. The content information application 287 is executed to receive verbal content 106 from users via the microphone 285, present responses via the speech synthesizer 288 and the audio device 286 and perform playback of sound effects that are defined by an audio script 237.

[0030] In some embodiments, the voice interface device 102 functions merely to stream audio from the microphone 285 to the query response service 218 and to play audio via the audio device 286 that is received from the query response service 218 that the query response service 218 identifies in an audio script 237. In these embodiments, the speech synthesizer 288 can be executed server side along with the content information application 287 in the computing environment 203 to generate an audio stream. In other implementations, the voice interface device 102 can obtain an audio script 237 from the query response service 218 and execute the speech synthesizer 288 and the content information application 287 locally.

[0031] Next, a general description of the operation of the various components of the networked environment 200 is provided. To begin, a content publisher can create an audio script 237 that is associated with a piece of content, such as a book, comic, song, album, or another piece of media. The audio script 237, as noted above, can specify various sound effects that should be played at particular portions during performance of a piece of content. For example, during the reading of a book or the singing of a song, the audio script 237 can specify sound effects, such as effects noises or sounds, background music, accompanying voices, background singing, or other types of sound effects that can be played at specific moments.

[0032] The audio script 237 can be created manually or with a content editing tool by a publisher. For a particular sound effect in an audio script 237, one or more cue words or phrases can be defined that are associated with the sound effect. In other words, the audio script 237 can specify that a particular sound effect should be played by the audio device 286 when one or more cue words or phrases are detected by the voice interface device 102 via the microphone 285. The audio script 237 can also specify whether a particular sound effect should be played once, twice, thrice, etc., or looped indefinitely. The audio script 237 can also specify whether a particular sound effect should be terminated upon detection of one or more termination cue words.

[0033] In some examples, the audio script 237 can associate sound effects with multiple cue words or phrases so that uniqueness can be guaranteed or so that the odds of uniqueness can be increased. In one scenario, the audio script 237 can associate sound effects with a quantity of cue words necessary to uniquely identify a context within a piece of content. For example, a sound effect can be associated with as many cue words as necessary to uniquely identify a particular line in a book or song from among the remaining text of the work. As another example, a sound effect can be associated with three cue words. In another example, a content information application 287 can be configured to identify the context within a piece of content in other ways, as will be discussed below.

[0034] A user can acquire rights to a piece of content, such as a book, song, or other piece of media that can be associated with an audio script 237. The user can initiate playback of the audio script 237 along with the user's performance of the piece of content. In other words, a book can be read aloud or a song can be sung aloud by one or more users such that the voice interface device 102 can capture verbal content associated with the performance of the content. To initiate accompaniment of the audio script 237, the user can speak a wake word or phrase that activates the listening capabilities of the voice interface device 102. In some examples, the user can also launch an application or otherwise activate the listening capabilities of the voice interface device 102 such that the content information application 287 is activated.

[0035] Next, the user can speak a command that instructs the content information application 287 to activate an accompaniment mode and retrieve an audio script 237 that corresponds to a particular content title 233. In one example, the command can be "Read along with me for Harry Potter and the Sorcerer's Stone." As another example, the command can be "Sing along for Starman by David Bowie." In other words, the command can include an instruction to activate an accompaniment mode and a reference to a content title 233 so that the content information application 287 can determine which audio script 237 is appropriate.

[0036] In some embodiments, the content library 227 can contain an audio script 237 that corresponds to any unrecognized content title or a generic audio script 237 that can be associated with content that does not have a specific audio script 237 defined in the content library 227. In this scenario, the audio script 237 can define sound effects that can be played along with any content that is read aloud or performed by the user. When the user activates an accompaniment mode of the content information application 287 through a verbal command, the audio script 237 can specify that once certain cue words are spoken by the user, certain sound effects should be played. In one scenario, the audio script 237 can define multiple or different sound effects for certain cue words or phrases from which the content information application 287 can select or rotate. In this way, a more varied user experience can be provided rather than an experience in which the same sound effects are played every time certain cue words or phrases are played.

[0037] In some embodiments, before initiating playback of an audio script 237, the content information application 287 can determine whether the user is entitled to access the audio script 237 based upon the entitlements or a transaction history {e.g., a purchase history) associated with the user account. For example, a certain audio script 237 may only be available to users who have purchased a particular book or song, so the content information application 287 and/or query response service 218 can first verity the user's access rights to an audio script 237 before initiating playback.

[0038] In one embodiment, the content information application 287 can identify a word in verbal content 106 that includes an instruction to enter an accompaniment mode. The word can be one of many words that are defined as action words for the mode. Next, the content information application 287 can perform a speech-to-text conversion of the remaining words in the verbal content 106 and provide the converted text to the query response service 218. In some examples, another library, service, or application executed by the voice interface device 102 can convert the verbal content 106 to speech on behalf of the content information application 287. The query response service 218 can then determine whether the text corresponds to a content title 233.

[0039] In some alternative embodiments, the content information application 287 can simply provide an audio stream or audio file that includes the verbal content 106, which the query response service 218 can convert to text without assistance from the content information application 287. Additionally, the content information application 287 can query the content library 227 directly and identify an appropriate audio script 237 based upon the verbal content 106.

[0040] As noted above, a particular audio script 237 can be associated with multiple content titles 233. In one scenario, the query response service 218 can perform an unassisted disambiguation process in which the query response service 218 determines whether the text received from the content information application 287 corresponds to a piece of content that is associated with multiple content titles 233. The query response service 218 can identify the audio script 237 corresponding to the text in this scenario with the benefit of the content titles 233 stored in the content library 227.

[0041] In some scenarios, the query response service 218 may be unable to identify a single content title 233 in the verbal content 106. In this case, the query response service 218 can identify a number of choices from which a user can select. In other words, the query response service 218 can identify candidate content titles 233 that are associated with the highest confidence score as being the content title 233 verbalized by the user in a command to initiate an accompaniment mode. In this scenario, the query response service 218 can provide the candidate choices to the content information application 287, which can solicit the user to select from among the choices. The content information application 287 can present the choices to the user by causing a textual response to be read out to the user via the speech synthesizer 288 and the audio device 286. The content information application 287 can obtain a response from the user in the form of verbal content 106 that identifies one of the choices and then obtain the corresponding audio script 237 from the query response service 218. [0042] In some cases, the query response service 218 or content information application 287 can identify a song lyric or textual content of a book within the verbal content 106. In this scenario, a user may simply begin reading a book or singing a song, and the verbal content 106 captured by the content information application 287 can be analyzed to determine whether it corresponds to textual content 235 of a piece of content. If a particular piece of content can be detected based upon such an analysis, the content information application 287 can immediately begin playback of the appropriate audio script 237.

[0043] Upon identifying the audio script 237 corresponding to the text in the verbal content 106, the query response service 218 can transmit all or a portion of the audio script 237 to the content information application 287. In some examples, the query response service 218 can also transmit the textual content 235 of the content to the content information application 287 to assist in determining the context or a location within the content that corresponds to verbal content 106 captured via the microphone 285. In some embodiments, the content information application 287 can activate a book or story mode if the content type 231 corresponds to a book or story. The content information application 287 can also activate a karaoke or song mode if the content type 231 corresponds to a song.

[0044] Upon receiving the audio script 237, the content information application 287 can then activate a listening process that determines a context of the content being read aloud or performed by the user. The context of the content can be determined based upon an analysis of verbal content 106 captured via the microphone 286 as well as the textual content 235 and/or textual indicators specified by the audio script 237. In this sense, by determining the context of the content, it is meant that the content information application 287 determines a location within the content that a user is reading aloud, singing, or otherwise performing. In other words, the content information application 287 can determine a chapter, verse, line, or specific word within a book or song that corresponds to the verbal content 106 captured via the microphone 285.

[0045] In one example, the content information application 287 can identify words in the verbal content 106 that uniquely identify a particular location within the content. In one embodiment, the content information application 287 can also assume that the content is being read from the beginning when a user commences an accompaniment mode. In another example, a user may verbally indicate a chapter, page number, or verse, or other contextual indicator from where playback should begin. Then, as the user reads or performs the content, the content information application 287 can track the user's position within the content to detect cue words defined by the audio script 237.

[0046] As noted above, the audio script 237 can specify sound effects with particular points within the content by specifying cue words that are associated with particular sound effects. For example, when a certain line of a book is reached, the audio script 237 can specify that a particular sound effect should be played. Accordingly, once content information application 287 detects the cue words that are specified by the audio script 237, the content information application 287 can initiate playback of the sound effect.

[0047] In one embodiment, the audio script 237 can specify multiple cue words associated with the sound effect such that the cue words uniquely identify a particular portion of the content. By associating multiple cue words with a particular sound effect, the audio script 237 can improve the chances that another portion of the content, when spoken or sung by the user, does not cause a false positive association with a particular sound effect. For example, the audio script 237 can associated at least three cue words with a sound effect in one example.

[0048] In an alternative embodiment, content information application 287 can maintain a buffer of verbal content 106 captured since the user initiated the accompaniment mode. In this way, the content information application 287 can, based upon an analysis of the buffer, which can be a running analysis, identify a distinction between different portions of the content. For example, the content information application 287 can distinguish between a first verse in a song and a second verse in a song even if the two verses contain the same chorus or identical textual content because the content information application 287 can follow the process of the user through the content by performing a running analysis of the buffer.

[0049] As noted above, certain sound effects, in addition to being associated with one or more cue words at which playback of the sound effect should commence, can also be associated with one or more termination cue words at which playback of the sound effect should terminate. Accordingly, upon detection of the termination cue words associated with a sound effect in the verbal content 106, the content information application 287 can terminate playback of the sound effect. For example, in the case of background music or noise that repeats, the termination cue words can indicate when playback of the repeating sound effect should terminate.

[0050] In the context of this disclosure, sound effects can take the form of noises, music, voices, or other effects sounds that can be played back through the audio device 286 by the content information application 287. Sound effects specified by the audio script 237 can also take the form of musical notes, percussion hits, or other musical effects that can be played back by the voice interface device 102 or generated by a musical instrument digital interface (MIDI) or similar interface with which the voice interface device 102 is equipped. Sound effects can also be layered. In this sense, a particular sound effect can be initiated at particular cue words and terminated at termination cue words that occur later in the content. In between these cue words and termination cue words, additional sound effects can also be triggered and terminated as specified by the audio script 237.

[0051] The content information application 287 can also detect completion of content corresponding to an audio script 237 by detecting the end of the content or termination keywords within the verbal content 106. In some embodiments, upon completion of a book or a song, the content information application 287 can terminate the listening process that listens for verbal content 106 and initiates playback of sound effects. In some cases, additional data 239 corresponding to a piece of content may indicate that a reward or promotion should be associated with a user account in response to completion of a piece of content. In some cases, the additional data 239 can indicate that a reward or promotion should be rewarded if the user reaches a certain point within the content, such as a particular chapter, verse, or other progress within the content. Accordingly, the content information application 287 can transmit such an indication to the query response service 218, which can update the user account with such a reward or promotion. [0052] Referring next to FIG. 3, shown is a flowchart that provides one example of the operation of a portion of the query response service 218 according to various embodiments. It is understood that the flowchart of FIG. 3 provides merely an example of the many different types of functional arrangements that may be employed to implement the operation of the portion of the query response service 218 as described herein. As an alternative, the flowchart of FIG. 3 can be viewed as depicting an example of elements of a method implemented in the computing environment 203 according to one or more embodiments. FIG. 3 illustrates an example of how the query response service 218 can receive a request for an audio script 237 and provide an appropriate audio script 237 that the content information application 287 can utilize to identify sound effects for playback to accompany verbal content 106 that is spoken or performed by the user.

[0053] Beginning with box 303, the query response service 218 receives a request for an audio script 237 from the content information application 287. The request can include a speech-to-text conversion of verbal content 106 captured by the voice interface device 102. In another embodiment, the request can include verbal content 106 itself, which can be processed by the query response service 218. At box 306, the query response service 218 can determine whether a content title 233 can be identified within the request from the content information application 287.

[0054] If a content title 233 cannot be identified within the request, the process proceeds to box 309, and the query response service 218 can initiate disambiguation so that a particular audio script 237 within the content library 227 can be identified. In one example, disambiguation can take the form of the query response service 218 identifying candidate content titles 233 that are associated with multiple pieces of content from the content library 227. The candidate content titles 233 can be identified by calculating a confidence score with multiple content titles 233 and provide the candidate content titles 233 to the content information application 287. For example, the query response service 218 can provide the two or three content titles 233 having the highest confidence score to the content information application 287.

[0055] In response to receiving the candidate content titles 233, the content information application 287 can prompt the user to select one of the candidates. If the query response service 218 can successfully perform disambiguation and select a content title, the process can proceed to box 315. If disambiguation is not successful, the process can proceed from box 312 to completion without identifying an audio script 237. In one example, the query response service 218 can return an error to the content information application 287. Otherwise, the process can proceed to box 315.

[0056] At box 315, the query response service 218 can identify an audio script 237 associated with the content title 233. The query response service 218 can then transmit the audio script 237 associated with the content title 233 to the content information application 287 at box 318. Thereafter, the process proceeds to completion.

[0057] Referring next to FIG. 4, shown is a flowchart that provides one example of the operation of a portion of the content information application 287 according to various embodiments. It is understood that the flowchart of FIG. 4 provides merely an example of the many different types of functional arrangements that may be employed to implement the operation of the portion of the content information application 287 as described herein. As an alternative, the flowchart of FIG. 4 can be viewed as depicting an example of elements of a method implemented in the voice interface device 102 according to one or more embodiments. FIG. 4 illustrates an example of how the content information application 287 can facilitate playback of an audio script 237 along with content that is read aloud or performed by a user can captured via a microphone 285.

[0058] At box 403, the content information application 287 detects a wake word, phrase, or sound from a user through a microphone 285. For example, users may say "Wake up!" and/or clap their hands together twice, which would be preconfigured respectively as a wake phrase or sound. In some embodiments, the content information application 287 is always listening and a wake word, phrase, or sound is not required. In various scenarios, the content information application 287 may be activated via a button press on a remote control, or via a user action relative to a graphical user interface of an application of a mobile device.

[0059] In box 406, the content information application 287 receives a command to play an audio script 237 via the microphone 285. The command can be obtained by capturing verbal content 106 via the microphone 285, performing natural language processing on the verbal content 106, and extracting a command verbalized by the user to enter an accompaniment mode. The verbal content 106 can also include a content title 233. At box 409, the content information application 287 can determine whether disambiguation of the content title 233 is required. If disambiguation is not necessary, the process can proceed to box 418. In one embodiment, the content information application 287 can transmit a speech-to-text conversion of verbal content 106 captured from a user via the microphone 285 to the query response service 218. The query response service 218 can return an indication of whether disambiguation of the content title 233 is required as well as provide candidate content titles 233 that can be selected by the user. If, at box 409, the content information application 287 determines that disambiguation of the content title 233 is required, then at box 412, the content information application 287 requests the user to select one of the candidate content titles 233 by presenting a follow-up question in order to prompt the user to select one of the candidate content titles 233.

[0060] At box 415, the content information application 287 can obtain a selection of the user of one of the candidate content titles 233 via the microphone 285. Then the process can proceed to box 418, where the content information application 287 can obtain the audio script 237 corresponding to the content title 233 from the query response service 218. At box 421 , the content information application 287 can initiate a listening process that obtains verbal content 106 from the microphone 285 and determines a corresponding context within a piece of content corresponding to the audio script 237.

[0061] At box 424, the content information application 287 can determine whether one or more cue words identified by the audio script 237 are in the verbal content 106. If not, the content information application 287 can continue to listen for verbal content 106 and continue to analyze the verbal content 106 to determine a context within the content corresponding to the audio script 237. If, at box 424, cue words corresponding to a sound effect are identified, the process proceeds to box 427, where the content information application 287 can either play or terminate the sound effect based upon whether the cue words correspond to initiating or terminating playback of the sound effect. At box 430, the content information application 287 can determine whether the end of the content corresponding to the audio script 237 has been reached. In one example, the content information application 287 can identify cue words corresponding to the end of the content, such as the end of a book or song. In another example, the content information application 287 can detect termination keywords that the user can speak, such as a command to cease playback of the audio script 237. If the end of the content has been reached or the accompaniment mode terminated by the user, the process can proceed to completion. If the end of the content has not been reached, the process can return to box 424, where the content information application 287 can listen for cue words and track the context of the content corresponding to the audio script 237.

[0062] With reference to FIG. 5, shown is a schematic block diagram of the computing environment 203 according to an embodiment of the present disclosure.
