| 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. |
