Document Type and Number:
WIPO Patent Application WO/2021/012734
Kind Code:
A1
Abstract:
An audio separation method and apparatus, an electronic device and a computer-readable storage medium. The method comprises: acquiring speech (S11); performing noise filtering on the speech (S12); extracting voiceprint feature data from the filtered speech, inputting the voiceprint feature data into a pre-set speech classification model for classification to obtain a classification result, encoding, according to the classification result, the speech corresponding to the same voiceprint feature data and storing same as a separate speech file, and performing separation processing on the speech (S13); and recognizing the speech after separation processing to acquire recognized text of the speech (S14). A pre-set speech classification model is used to perform separation processing on filtered speech according to the voiceprint features of the speech, and the speech after separation processing is recognized to acquire recognized text of the speech, so that the speech text of words spoken by different people in the speech can be recognized, thereby improving the accuracy of speech recognition.
