Title:
INFORMATION PROCESSING DEVICE, PROGRAM, AND INFORMATION PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/144857
Kind Code:
A1
Abstract:
The present invention is provided with: an audio speech likelihood calculation unit (103) that calculates audio speech likelihood from an audio signal including the voice of a subject person; a video speech likelihood calculation unit (104) that calculates video speech likelihood from a video signal indicating a video including the subject person; an environmental information determination unit (105) that determines audio reliability indicating the reliability of the audio signal and video reliability indicating the reliability of the video signal; a speech section detection unit (108) that adds a heavier weight to the audio speech likelihood when the audio reliability is higher, adds a heavier weight to the video speech likelihood when the video reliability is higher, calculates, by using the audio speech likelihood and the video speech likelihood, speech likelihood indicating a probability that the subject person is uttering speech in the audio signal and in the video signal, and detects, as a section of speech, a section where the calculated speech likelihood is higher than a predetermined threshold; and an audio recognition unit (109) that executes audio recognition on the audio signal in the section of speech.
