Does Speex have anything to do with the University of Sherbrooke?
No. I have written Speex while pursuing my Ph.D. at the University of Sherbrooke (2002-2005) in mobile robotics. Although I did my master with the Sherbrooke speech coding group (in speech enhancement, not coding), I was no longer associated with them when developing Speex. Furthermore, Speex does not make use of any code or proprietary technology developed in the Sherbrooke speech coding group.
