    (description "Sonic implements 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.  Sonic is a C library designed to be easily
integrated into streaming voice applications such as text-to-speech (TTS) back
ends.

The primary motivation behind Sonic is to enable the blind and visually impaired
to improve their productivity with speech engines, like eSpeak.  Sonic can also
be used by the sighted.")
