Hey all,
How can I process a sample of a normal human voice to sound like a quiet whisper that is muffled. The words should no longer be intellegible, but it should be recognized and a voice and sound as analog as possible.
Muffled as in the change of voice when heard through layers of clothing.
If you have any patches please send them along!
Thanks.

a quick idea attached, still a bit to do I guess ...

A muffled whisper? Are you sure it would then be intellegible? To muffle sound, try with a lowpass filter. To "whisperize" is not that easy.
Exerpt from http://www.csis.ul.ie/dafx01/proceedings/papers/verfaille_a.pdf "The regular whisperization is obtained by calculating the FFT of small input buffers (32 or 64 samples), and giving random values to the phase or to the modulus (cf. fig11)."
Vincent Verfaille wrote the article and have a web site about his thesis: http://adafx.free.fr/ -- Marc
I haven't tried it, but how about using convolution? You could try recording something like a sigh or other breath noise and convolving it with normal speech.

i think that's what CK's patch does.
but he uses noise~ instead of a breath sound. - the sigh or breath noise is gonna sound better though i reckon

If you want whisperization, you can use a phase vocoder and add some noise to the phase - this will make the voice sound more like whisper.

In this case a low pass filter higher order can do that. Combining it with whisperization could give you an interesting effect.

Maybe you could use the phase vocoder patch from help I07 and modify it...

Hi Ben,
You can use the lpc~ lpreson~ objects from ekext. Look at the lpc-cross-synthesis.pd patch. It's a little tricky to use, since you have to feed the audio output of lpc~ into the lpreson~ object thus: [ lpc~ ] | | [ *~ 0] | | | [ lpreson~]
I'm still not sure why this is, but you can then feed any signal into the lpreson~ and you'll have the formants of the voice imposed on whatever signal you choose. In order to muffle the voice, but still retain the excitation pattern, it might be worth trying a lowpass filter on the audio output of lpc~, fed into the lpreson~.
Best, Ed
