libspeex-dev - 1.2~rc1.2-1+b2 main

Speex is an audio codec especially designed for compressing voice at low
bit-rates for applications such as voice over IP (VoIP). In some senses,
it is meant to be complementary to the Vorbis codec which places a greater
emphasis on high-quality music reproduction.
