speech detection using autocorrelation
显示 更早的评论
i have a wav sample containg speech and noise.. how can i detect speech and noise using correlation function. (if we do correlation on wav sample,for speech the correlation coeff will be high and for noise it will be low..) how do i do it in matlab??

I'm not a speech expert but that doesn't sound like it would work. Do you have some published paper that says that that will work? Have you tried the corr() function? I doubt that you'd find correlation of my speech with your speech or anyone else's speech. What is going to be your reference waveform that you correlate "test" waveforms against?

I don't know the algorithm. Like I asked, did you try the corr() function?

I'm not sure what the desired output is, but that's what I expected. What is the desired output? Is it that a waveform contains spoken words? Any spoken words by any person at all? Or do you want to identify one particular person - the name of the person who spoke those words?
