WIPO Patent Application WO/2022/179253
Kind Code:
A1
Abstract:
A speech operation method for a device, comprising: acquiring a video captured by a camera (11); acquiring speech information captured by a microphone (12); detecting a face image in the video; extracting lip features and facial features of the face image; determining a time interval according to the lip features; capturing, according to the time interval, a corresponding audio clip in the speech information; acquiring voiceprint information according to the facial features; and performing speech recognition on the audio clip according to the voiceprint information, so as to acquire speech information. When using the speech operation method for a device to perform a speech operation of the device, there is no need to pre-determine a target user and pre-record voiceprint information of the target user, and when a plurality of users (1, 2) simultaneously use the device, voiceprint information of the plurality of users (1, 2) can be extracted autonomously, and the speeches are separated one by one. Also, voiceprint can be updated and registered autonomously. Using the speech operation method for a device to perform a speech operation on the device significantly improves the speech recognition effect of the device in a noisy situation or a situation where a plurality of users (1, 2) are speaking.
