Germain,

Look at application note 643
http://www.microchip.com/cgi-win/DownLoad.exe?/download/lit/appnote/00643a.pdf:1

It may be what you are looking for. When we were at the seminar, they
showed a voice synthesis application. I looked for the source code on
Microchips web site but I was unable to find it.

Hope this helps!
