语音信号处理实基于MATLAB的语音信号时域特征分析
要求:
按所学相关语音处理得的知识,通过网上学习、资料查阅,自己设计程序,给出某一语音信号的短时过零率、短时能量、短时自相关特征的分析结果,并借助时域分析方法检测所分析语音信号的基音周期(yu yin xin hao chu li)

matlab
语音信号进行分析、处理和设计。用MATLAB做变声器的原理是通过改变输入声音频率,进而改变声音的音色、音调,使输出声音在感官上与原声音不同。变声器是借助对声音音色和音调的双重复合改变,实现输出声音的改变。通过自己发声,共振峰频率的改变是基于重采样实现的(Speech signal analysis, processing and design. MATLAB do voice-changer works by changing the input frequency of the sound, and then change the sound of the tone, pitch, so that the output audio with the original sound in different senses. Voice Changer is the use of sound timbre and tone of the dual composite changes, realize the output sound changes. Through their own sound, formant frequency change is implemented based on resampling)
