Abstract

The invention discloses an intelligent track division method, device and system for monaural call recording, which are used for separating multi-person voices in monaural call recording, and the method comprises the following steps: preprocessing audio data of the call recording to obtain preprocessed audio data; performing frame attribute detection on the preprocessed audio data, and judging frame attribute information of each frame in the audio data; determining a voice starting point in the audio data according to the frame attribute information of each frame in the audio data, and deleting the audio data before the voice starting point to obtain pure voice audio data; and inputting the pure voice audio data into a track division model to obtain track division information of the pure voice audio data. According to the technical scheme, voice starting point detection is carried out firstly, interference is eliminated, only a pure voice part is reserved, and then actual speaker roles are separated out for subsequent ASR correct recognition.

Description

technical field [0001] The invention relates to the field of computer information processing, in particular to an intelligent tracking method, device and system for monophonic call recording. Background technique [0002] When recording a call on a traditional telephone, the call recording is usually in two channels, and it is easy to distinguish the vocal roles corresponding to different channels when restoring the content. With the development of Internet technology, Internet telephony and voice conferencing have gradually become popular. In order to reduce the requirements for network speed and improve call quality in Internet telephony and audio conferencing, monaural channels are often used. If call recording is also performed in mono recorded in the form of soundtracks. [0003] If such a monophonic recording is directly input into a speech recognition (ASR) system, since there is only one audio channel, the speaker of each utterance cannot be restored from the recogn...
