SPEECH PRESENCE PROBABILITY CALCULATING METHOD AND SYSTEM, SPEECH ENHANCEMENT METHOD AND SYSTEM, AND HEADPHONES

Title:

SPEECH PRESENCE PROBABILITY CALCULATING METHOD AND SYSTEM, SPEECH ENHANCEMENT METHOD AND SYSTEM, AND HEADPHONES

Document Type and Number:

WIPO Patent Application WO/2023/060400

Kind Code:

A1

Abstract:

The present description provides a speech presence probability calculating method and system, a speech enhancement method and system, and headphones. By comparing entropy of a speech presence probability and entropy of a speech absence probability, the speech presence probability and the speech absence probability in an iteration process are corrected to obtain a higher convergence speed and a better convergence result. Thus, the speech presence probability and noise covariance matrix estimation accuracy is higher, thereby improving the speech enhancement effect of MVDR.
