xercist writes "Xiph.org has added a new project to their plate of goodies- Speex. Speex is an audio codec specifically for, you guessed it, voice. It has integration with Xiph's OGG container, but is mainly being used right now for VOIP. There is currently an XMMS plugin available, and is also supported by LinPhone, OpenH323, and GnomeMeeting. Asterisk PBX is working on adding support. This is not a new project -- Jean-Marc Valin has been hard at work writing the codec for quite a while now. However, Jean-Marc is now a full-fledged member or the Xiph.org team, and in celebration, Speex beta one is being released. Xiph.org has brought you (or is currently working on bringing you) Vorbis, Tremor, Theora, Tarkin, Icecast2, cdparanoia, now Speex, and, of course, the Moaning Goat Meter. This is a LOT to do, so please donate to show your support."
