一种基于MMSE-LSA和VAD的语音增强算法
A Speech Enhancement Algorithm Based on MMSE-LSA and VAD
摘要
Abstract
The minimum mean square error of log-spectral amplitude estimator (MMSE-LSA) algorithm is analyzed in detail by introducing the characteristics of speech enhancement, and voice activity detection (VAD) algorithm matching with MMSE-LSA algorithm is proposed. This scheme is simple and easy to implement and its speech enhancement effect is good. In addition, it can track the changes of background noise dynamically. Finally, the enhancement effect of MMSE-LSA is compared with that of other algorithms by the analysis of simulation.关键词
