The Text To Speech module allows you to add text to speech (TTS) instances on your PBX. When entered as a destination in your call path, the system will play the text entered using the selected TTS engine. The call will then continue on to the target destination defined in the instance.

Depending on the TTS engine you have installed, you may want to experiment with the spelling of words phonetically to get the speech engine to pronounce them in the manner you desire. For
example, if you type the number “0” but want the system to say “Oh” instead of “Zero,” you would want to type the word “Oh.”
