GNOME text-to-speech library

 The GNOME Speech library gives a simple yet general API for programs
 to convert text into speech, as well as speech input.
 .
 Multiple backends are supported by the GNOME Speech library.
 The Festival, Espeak and speech-dispatcher backends are provided
 by default in this package; other backends that require proprietary
 software are available via separate packages (gnome-speech-dectalk
 and gnome-speech-swift).
