Re: evaluation of speech enhancement algorithm. How?

So you are trying to make the voice sound like you had not added the
pink noise in the first place? Can you give some idea what your
relative speech/noise levels are?

Where did the whitening filter come from?

When you turn the noise level down and analyze/synthesize the waveforms
do the original (clean) signal and reconstructed signal look similar on
a point-by-point basis? If not, then subtracting waveforms and looking
at errors is not the way to evaluate the 'quality'.

Do some searching on "LPC analysis in noise".
