Abstract: A sound processing system is provided and is executed by a processor. The processor acquires a video/audio file from video/audio files. The processor controls a video/audio processing chip to build a voiceprint feature model of each section for use in speaker recognition, and to identify the speaker of each section based on comparison of the built voiceprint feature model of the acquired video/audio file and the voiceprint feature models of speakers stored in a storage unit. The processor generates a tag file recording relationships between the plurality of sections of the acquired video/audio file and the speakers according to the identification result. A sound processing method is also provided.
