VOICE RECOGNITION METHOD AND DEVICE AND COMPUTER READABLE STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2020/140609

Kind Code:

A1

Abstract:

A voice recognition method and device and a computer readable storage medium. The method comprises: obtaining a first digital voice signal to be detected, wherein the first digital voice signal is composed of digital ciphers, and the digital ciphers are composed of multiple digits (S101); performing preset segmentation processing on the first digital voice signal to obtain multiple second digital voice signals, wherein each second digital voice signal is determined by a digit (S102); processing the second digital voice signals according to a preset signal processing method, determining logarithmic Mel power spectra corresponding to the second digital voice signals, and extracting target feature information of the second digital voice signals from the logarithmic Mel power spectra (S103); recognizing the target feature information of the second digital voice signals on the basis of a neural network model so as to obtain target digits corresponding to the second digital voice signals (S104); and determining a target digital cipher corresponding to the first digital voice signal according to the target digits corresponding to the second digital voice signals (S105). The method improves the performance and validity of voice recognition.
