Abstract

The embodiment of the disclosure discloses a voice segmentation model training method and device, electronic equipment and a computer readable storage medium. The training method of the voice segmentation model comprises the following steps: acquiring a voice feature map of a sample voice file; acquiring annotation information of a target voice in the voice feature map; initializing model parameters of a voice segmentation model; inputting the voice feature map into the voice segmentation model to obtain prediction information of a target voice output by the voice segmentation model; calculating an error between the prediction information and the annotation information according to a target function; updating parameters of the voice segmentation model according to the error; and inputtingthe voice feature map into the voice segmentation model after parameter updating to iterate the parameter updating process until the error is less than a first threshold. According to the method, thespeech segmentation model is trained through the speech feature image, and a technical problem of inaccurate speech segmentation caused by complex speech signals in the prior art is solved.

Description

technical field [0001] The present disclosure relates to the field of speech segmentation, and in particular to a training method, device, electronic equipment and computer-readable storage medium of a speech segmentation model. Background technique [0002] As a means of human-computer interaction, speech recognition technology is of great significance in liberating human hands. With the emergence of various smart speakers, voice interaction has become the new value of the Internet portal. More and more smart devices have joined the trend of voice recognition and become a bridge for communication between people and devices. Voice segmentation technology is a branch of speech recognition technology, which is used to divide a piece of voice into different categories according to time periods, such as segmenting the voices of non-simultaneous speakers in a piece of voice, voice endpoint detection and wake-up word alignment etc., all belong to the category of speech segmentati...
