Speech Dispatcher:

Key features:

  * Common interface to different TTS engines
  * Handling concurrent synthesis requests -- requests may come
    assynchronously from multiple sources within an application and/or
    from different applications
  * Subsequent serialization, resolution of conflicts and priorities of
    incomming requests
  * Context switching -- state is maintained for each client connection
    independently, event for connections from within one application
  * High-level client interfaces for popular programming languages
  * Common sound output handling -- audio playback is handled by Speech
    Dispatcher rather than the TTS engine, since most engines have limited
    sound output capabilities

What is a very high level GUI library to graphics, Speech Dispatcher is
to speech synthesis. The application neither needs to talk to the devices
directly nor to handle concurrent access, sound output and other tricky
aspects of the speech subsystem.
