Just as Vorbis competes with royalty-based algorithms like MP3 and AAC, Speex shares space in the speech codec market with GSM-EFR and the G.72x algorithms, such as G.729 and G.722. Speex also has many features that are not present in most other codecs. These include variable bit rate (VBR), integration of multiple sampling rates in the same bitstream (8 kHz, 16 kHz, and 32 kHz), and stereo encoding support. Also, the original design goal for Speex was to facilitate incorporation into Internet applications, so it is a very capable component of VoIP phone systems.
