Title:
VOICE RECOGNITION METHOD AND APPARATUS, AND ELECTRONIC DEVICE, STORAGE MEDIUM AND COMPUTER PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2024/093578
Kind Code:
A1
Abstract:
A voice recognition method and apparatus, and an electronic device, a storage medium and a computer program product, which are applied to the fields of artificial intelligence and games. The method is executed by the electronic device. The method comprises: performing sliding window interception on a voice signal to recognized, so as to obtain at least two sub-voice signals (S501); by means of a pre-trained embedded feature representation system, performing voice feature extraction on each sub-voice signal, so as to obtain a sub-voice embedded representation feature of the corresponding sub-voice signal (S502), wherein the embedded feature representation system comprises a first-stage feature extraction network and a second-stage feature extraction network, the first-stage feature extraction network is used for performing first-stage voice feature extraction on the sub-voice signal to obtain a first-stage voice feature, the second-stage feature extraction network is used for performing second-stage voice feature extraction on the sub-voice signal on the basis of the first-stage voice feature, and the feature extraction precision of the second-stage voice feature extraction is greater than the feature extraction precision of the first-stage voice feature extraction; acquiring an embedded representation feature of each contrastive word in a preset contrastive word library (S503); according to the sub-voice embedded representation feature and the embedded representation feature of each contrastive word, performing voice recognition on each sub-voice signal, so as to obtain a sub-voice recognition result (S504); and according to the sub-voice recognition result of each sub-voice signal, determining a voice recognition result corresponding to the voice signal to be recognized (S505).
