Hello, Friends, At first I should say sorry, because my question maybe is not related with Speex dev. Since Speex codec is based on CELP technology, so if we change the pitch intentionally when encoding/decoding spx files, can we get the Pitch Shifting effect without speech formant changed? Regards, James.

However, expect the results not to be as good as for a "real" (originally designed for that) pitch shifter. Jean-Marc -- Jean-Marc Valin <Jean-Marc.Valin@USherbrooke.ca> Universit? de Sherbrooke
