To change a TTS type:
The system displays the Text-to-Speech Configuration screen. For information about this screen, see Text-to-Speech Configuration screen.
Note:
The value that you select for the Engine field must be consistent with the engine that is running on the TTS server.
The system displays information about the success or failure of the administration attempt.
Administration changes do not take effect until you stop and start the voice system (see Stopping and starting the voice system).
