+    (description "Sonic is a simple algorithm for speeding up or slowing down
+speech.  However, it's optimized for speed ups of over 2X, unlike previous
+algorithms for changing speech rate.  The Sonic library is a very simple ANSI C
+library that is designed to easily be integrated into streaming voice
+applications, like TTS back ends.
+
+The primary motivation behind Sonic is to enable the blind and visually impaired
+to improve their productivity with open source speech engines, like espeak.
+Sonic can also be used by the sighted.  For example, Sonic can improve the
+experience of listening to an audio book on an Android phone.")
