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.")

    (synopsis "Speech synthesis system")
    (description "Festival offers a general framework for building speech
synthesis systems as well as including examples of various modules.  As a
whole it offers full text to speech through a number APIs: from shell level,
though a Scheme command interpreter, as a C++ library, from Java, and an Emacs
interface.  Festival is multi-lingual though English is the most advanced.
The system is written in C++ and uses the Edinburgh Speech Tools Library for
low level architecture and has a Scheme (SIOD) based command interpreter for
control.")
