Abstract

The invention belongs to the technical field of multimedia information processing, and particularly relates to a portrait voice and video synchronous calibration device and system, and the device comprises a mouth shape recognition module, an error correction module, an emotion rendering module, a background sound effect module, a statistical evaluation module, and a comprehensive analysis module.The portrait voice and video synchronous calibration device and system is characterized in that the mouth shape recognition module comprises a video acquisition unit, a video analysis unit, a voice acquisition unit, a voice analysis unit, a mouth shape comparison unit and a matching input unit. The video acquisition unit is used for acquiring a video image. The video analysis unit is used for analyzing the acquired video. The voice acquisition unit is used for acquiring dubbing data. The voice analysis unit is used for analyzing the acquired dubbing information. The mouth shape comparison unit is used for comparing whether the mouth shape in the video is consistent with the voice or not. The portrait voice and video synchronous calibration device and system is mainly used for solving theproblems that an existing voice and video synchronous calibration system cannot achieve system self-adjustment and meanwhile cannot modify dubbing.

Description

technical field [0001] The invention belongs to the technical field of multimedia information processing, and specifically relates to a voice and video synchronous calibration device and system for portraits. Background technique [0002] With the popularity and development of multimedia and the Internet, portrait voice and video applications are used in various fields, such as talk entertainment programs, network anchor programs, and large-scale open online courses. The audio information and video information used in portrait audio and video are generally recorded separately by different hardware, and then comprehensively processed by a computer to synthesize a audio and video file that can be played directly, and subtitles are usually added when necessary. During the recording process, due to hardware or network problems, the voice information and video information will be out of sync. Traditional voice and video synchronization calibration generally uses manual playback ...
