改进谱减法语音增强算法的研究
Research on Speech Enhancement of Improved Spectral Subtraction Algorithm
摘要
Abstract
For the speech signal,voice quality is greatly affected by the noise. Speech enhancement techniques must be used to suppress background noise,improving voice quality and voice clear degrees. The speech enhancement is to get the speech as original as possible from the speech signal with noise. The spectral subtraction speech enhancement is utilized broadly because it is simple and easy for the re-al-time processing. In this paper,the basic principle of algorithm of the spectral subtraction is presented. Aiming at reducing annoying musical noise in the standard spectral subtraction algorithm,the principle of two kinds of typical improved spectral subtraction is ana-lyzed. Experimental results show that the proposed algorithm reduces the musical noise effectively and improves the speech quality.关键词
