-Speex is a patent-free compression format designed especially for
-speech. It is specialized for voice communications at low bit-rates in
-the 2-45 kbps range. Possible applications include Voice over IP
-(VoIP), Internet audio streaming, audio books, and archiving of speech
-data (e.g. voice mail).

-This is the DSP package, see the speex package for the codec part.

+Speex is an Open Source/Free Software patent-free audio compression format designed for speech.
+The Speex Project aims to lower the barrier of entry for voice applications by providing a free
+alternative to expensive proprietary speech codecs. Moreover, Speex is well-adapted to Internet
+applications and provides useful features that are not present in most other codecs. Finally,
+Speex is part of the GNU Project and is available under the revised BSD license.
