Description:
Speech Dispatcher: Development libraries and header files
Speech Dispatcher provides a device independent layer for speech synthesis. It supports various software and hardware speech synthesizers as backends and provides a generic layer for synthesizing speech and playing back PCM data via those different backends to applications. . Various high level concepts like enqueueing vs. interrupting speech and application specific user configurations are implemented in a device independent way, therefore freeing the application programmer from having to yet again reinvent the wheel. . This package contains static library, and C headers needed for programs linked with the shared or static library.
