Title:
SPEECH ENDPOINT DETECTION METHOD, APPARATUS AND DEVICE, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/105570
Kind Code:
A1
Abstract:
A speech endpoint detection method, apparatus and device, and a computer readable storage medium. The method comprises: extracting time-domain signals of all data frames in a speech signal acquired in real time, and converting the time-domain signals into frequency-domain spectrum signals (S10); sequentially traversing the frequency-domain spectrum signals, determining a current frequency-domain spectrum signal corresponding to the traversed current data frame, and calculating a short-time energy entropy ratio of the current data frame according to the current frequency-domain spectrum signal (S20); detecting whether the short-time energy entropy ratio is greater than an initial detection threshold of the speech signal (S30); and if the short-time energy entropy ratio is greater than the initial detection threshold of the speech signal, moving the current data frame to a preset speech frame buffer, and determining a speech paragraph endpoint of the speech signal according to all the data frames in the speech frame buffer (S40). The present application improves the accuracy of speech endpoint detection.
