iir
语音信号的iir滤波器设计,从带有噪音的信号中提取原始声音.目前，MP3播放器一般功率放大器的工作频率范围就是这个范围。但是大部分有用的和可理解的信息的频率在200到3500Hz之间。所以我们可以在这个范围间滤波，达到使声音可理解的要求。现将数字滤波器的设计指标设为通带截止频率fb=600HZ,阻带频率fc=1200HZ,通带波纹Ap=1dB，阻带波纹As=40dB,要求确定H(z)。(design of the iir filter, get the original voice without noise)

exercise319b
Splice out the voiced plosive “b” in theword “be” and synthesize aword with an increase in the
voice onset time of the “b.” What is the perceptual effect? Is it possible to transform the voiced
plosive “b” to the unvoiced plosive “p” with this change in the voiced onset time? Consider
attributes such as vocal cord vibration and aspiration. (In splicing, display the waveform and
spectrogram of the word “be” and use the MATLAB function ginput.m.) Optional: If your
transformed sound does not sound like a “p” then, again considering vocal cord vibration and
aspiration, make a more accurate transformation.
