I have been implementing VOIP in our mobile application. In voice encoding/decoding, I heard that the SPEEX codec is good for improving quality. Eventhough it has good quality, I have afraid to use it because in speex document they mentioned as "Speex is not designed for mobile phones but rather for packet networks and voice over IP (VoIP) applications". Could any one knows why SPEEX codec is not suitable for mobile applications however it has lot of features rather than G711, G722 ...etc?
