Like @Jonathan Schulenberg said to get true TTS you’ll need a supported vendor. There are two other options depending on your use case. You can create a prompt similar to what you’re doing and concaténate system prompts for very simple TTS like numbers. The other option would be to use something like Google TTS to create prompts on the fly for you. This is much more involved as you need to send the request to the cloud and then wait for it to be processed, you then download it, and save it, then play it to your caller. It’s been years since I’ve done that but it does work and it’s possible within UCCX.
