| 摘 要： | 语音信号处理是语音学与数字信号处理技术相结合的交叉学科.将语音当做一种特殊的信号,即一种“复杂向量”来看待.通过调用处理数字信号工具MATLAB里的命令函数,利用数字信号处理的知识来解决问题.像给一般信号做频谱分析一样,也分析了语音信号的频谱,即利用设计的多种数字滤波器,比如:FIR低通滤波器、高通滤波器、带通滤波器和...

| Abstract: | The speech signal processing is the cross-discipline which combines the voice science with the digital signal processing technology.The voice is taken as a special signal,i.e.a complex vector.By using the command functions in the digital signal processing tool-MATLAB,the digital signal processing can solve many problems.The spectrum of voice signals are analyzed,which is the same as the spectrum analysis of common signals.A variety of digital filters(FIR low-pass filters,high pass filters,band-pass filter a... |
