Title:
METHOD FOR ESTIMATING SIGNAL-TO-NOISE RATIO FOR NOISE SUPPRESSION, AND USER TERMINAL
Document Type and Number:
WIPO Patent Application WO/2018/086444
Kind Code:
A1
Abstract:
A method for estimating signal-to-noise ratio for noise suppression, and a user terminal. The method may comprise: estimating preestimated priori signal-to-noise ratio of a current audio frame (101); computing, according to the preestimated priori signal-to-noise ratio, an estimated value of an MMSE corresponding to the preestimated priori signal-to-noise ratio of the current audio frame (102); computing a speech presence probability of the current audio frame (103); and estimating final priori signal-to-noise ratio of the current audio frame with reference to the speech presence probability and the estimated value (104).
