Abstract
An apparatus and a corresponding method for voice processing are provided. The apparatus includes a sound receiver, a camera, and a processor. The sound receiver receives a sound signal. The camera takes a video. The processor is coupled to the sound receiver and the camera. The processor obtains a voice onset time (VOT) of the sound signal, detects a human face in the video, detects a change time of a mouth contour of the human face, and verifies at least one preset condition. When all of the preset conditions are true, the processor performs speech recognition on the sound signal. The at least one preset condition includes that a difference between the VOT and the change time is smaller than a threshold value.
