Hi,

How can I convert MALE voice into FEMALE voice?
Which filters provide the best conversion ?

Regards
Sandeep

This is one of the greatest effects in vocoders. I remember doing it
once to Amitabh Bacchan's Voice. Hope there are no fans around. Of
Course there was a bug. I dare not do it intentionally :-)

I guess using only a filter wouldn't be good enough. If you use a
parameteric codec, which extracts the pitch and encodes it as one of
the parameters just changing it to a higher value should make the
voice sound feminine on decoding. This technique would be valid for
codecs like LPC-10,CELP(G.729,AMR) which encode pitch info, but not
for audio codecs (MP3 etc).

this is a pretty humorous thread, but i'll add another serious note...

it depends on how the codec reconstructs the audio with the parameter
change.  one thing to look into is a sorta PSOLA method that, using a pitch
detector, windows off little wavelets or grains and then outputs them at
another rate.  higher rate pitches it up and a lower rate pitches it down.
independent of the pitch shift is the formant shift that can be accomplished
by stretching or scrunching the wavelets.  a formant shift up and a pitch
shift up by a different amount might do it.

My small contribution if you just can satisfy of changing the picth of the
male voice is to use some basic picth shifting technique like this one:

have fun !

I suspect modifyng the cepstrum produces the best results.

The cepstrum is used in speech synthesis and speech analysis.

Ha.  When I read Sandeep's "Subject" I laughed out 
loud.  I thought of several clever (non-technical) 
responses, but thought "No Rick.  Don't be 
a wisecracking smartass.  KEEP YOUR THOUGHTS 
TO YOURSELF."

So, you and Tom beat me to the punch.
Am so glad that there are other "wiseguys"
(not in the Mafioso sense) in this group.
