摘要
环境噪声会影响语音质量,严重的情况下语音将完全淹没到噪声中,无法分辨。语音增强就是从带噪语音信号中提取尽可能纯净的原始语音。本文对目前一些主要的语音增强方法做了研究,分析了各种方法的优缺点。在实际应用时,要根据具体的噪声情况和特定环境,选用不同的语音增强方法或语音增强方法的组合,来达到最好的语音增强的效果。
The environmental noise will affect the quality of speech, in the serious circumstances, it will submerge the speech, so the speech cant be detected. The speech enhancement is to get the speech as original as possible from the speech signal with noise. This paper studies on the main methods for the speech enhancement, and analyses their advantage and weakness. In the actual application, for the best effect of speech enhancement it should use different methods or their combination according to the specific noise and the given environment.
