基于MATALB的语音处理系统设计

he article elaborates the concrete step of the processing which carry on speech signal with the Matlab，and its purpose is mainly to improve the quality of voice. The text is divided into two parts to introduce it, speech analysis and speech enhancement. The speech analysis part gives a brief introduction of the pretreatment, and suggests the short time-domain analysis techniques. In the Speech Enhancement part, noise reduction is introduced through the introduction of acoustic, and it introduces several methods about speech enhancement by noise reduction, among which the improved spectral subtraction method just is the focus of this paper.
