Document Type and Number:
WIPO Patent Application WO/2022/134833
Kind Code:
A1
Abstract:
The present application relates to the technical field of artificial intelligence. Provided are a speech signal processing method, apparatus and device, and a storage medium, which are used for improving the recognition accuracy for valid short speech. The speech signal processing method comprises: acquiring a target short speech segment of a speech signal to be processed, and extracting a target audio feature of the target short speech segment; acquiring a target classification label from a preset short speech segment according to the target short speech segment, the target classification label comprising an interrogative tone, a normal indicative tone and/or a false-alarm noise; classifying the target audio feature by means of a target neural network model and the target classification label to obtain an initial recognition type and a target confidence coefficient; determining the initial recognition type, the target confidence coefficient of which is greater than a preset threshold value, as a target recognition type; and filtering said speech signal according to the target recognition type so as to obtain a target speech signal. In addition, the present application further relates to blockchain technology, and a speech signal to be processed can be stored in a blockchain.
