Title:
SPEECH EVENT DETECTION METHOD AND APPARATUS, ELECTRONIC DEVICE, AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/116420
Kind Code:
A1
Abstract:
A speech event detection method, a speech event detection apparatus (100), an electronic device (1), and a computer readable storage medium, relating to the artificial intelligence technology. The method comprises: obtaining an audio under detection, and performing acoustic feature extraction on the audio to obtain a speech frame feature sequence (S1); performing feature analysis on the speech frame feature sequence by using a self-attention mechanism-based classification model to obtain a hidden state sequence to be identified (S2); performing event identification on the hidden state sequence by using the classification model to obtain an event label sequence (S3); and performing smoothing processing on the event label sequence to obtain a speech event detection result corresponding to a speech under detection (S4). The present invention relates to the blockchain technology, and an audio under detection is stored in a blockchain node. Stability and accuracy of speech event detection are improved.
