Hi
My teacher asked me to program this thanks to Matlab, but I am not able to understand anything: "Indeed, we first compute
the short-time magnitude spectrum and phase spectrum of
the segment in a neighborhood (32 ms) of the sample
Note that the spectra are obtained through first multiplying
the segment by a 256-point Hamming window followed by
performing fast Fourier transform (FFT) analysis. Moreover,
such operations are carried out for each sample. Second, we
compute the short-time magnitude spectra of four neighboring
segments which overlap with the original segment by 12 or
24 ms (i.e., two of the neighboring segments are obtained by
shifting the analysis window 8 ms back and forth into the
past and into the future, and two others 20 ms into the past
and into the future). Third, we generate a “smooth” magnitude
spectrum by taking the minimum of the five magnitude spectra
for each frequency bin."
Does anyone know how to do that?
Thanks
Laure

Thank you very much for your answer, it has been very use full.
If any has an other piece of advice...

Hi,
I really would like to obtain, the codes the algorithm in matlab for this method of signal processing : "Kalman-Filtering Speech Enhancement Method Based on a Voiced-Unvoiced Speech Model". Does any one know how I can find them?
Thank you

I have no idea how to implement this thank to Matlab.
I am sorry, but I din't know how this site worked, so I think I made bad manipulations
Thank you
Laure
