A Voice Activity Detection Method Based on TEE

Abstract

To solve the problem of low accuracy of voice activity detection under low SNR, this paper proposes a voice activity detection method based on TEE. Firstly, TEE feature parameter is proposed and used for speech feature extraction; then, the superiority and real-time performance of TEE algorithm are verified theoretically; Finally, TEE is combined with the double threshod method based on FCMC and BIC for the voice activity detection. The experiment proves that the voice activity detection method has high accuracy.
