Document Type and Number:
WIPO Patent Application WO/2021/179424
Kind Code:
A1
Abstract:
A speech enhancement method combined with an AI model, a system, an electronic device and a medium. The speech enhancement method combined with an AI model comprises the following steps: acquiring a speech existence probability according to a target AI model (S11); obtaining noise power according to the speech existence probability (S12); obtaining a priori signal-to-noise ratio according to the noise power (S13); and obtaining a speech enhancement gain according to the prior signal-to-noise ratio (S14). The present invention can improve the intelligibility of a speech in a complex noisy scenario, and can also improve the performance of voice trigger detection and speech detection functions.
