I've found that Amazon Polly NTTS provides a much more natural and accurate voice than Google TTS inside of Genesys. I don't know if you can do what you are asking, but you can manipulate the playback quite a bit using the markup language. In the end, I've found that using the Polly console to test playback and tweak it via the console, then downloading it to a wav file to be best. I put those wav files into the IVR whenever we have static prompts / statements, then use the Polly TTS engine when it needs to playback numbers, or any other dynamic statements. This way, there are a lot less API calls to the TTS engine, the IVR runs more reliably, and you get a unified voice. There are caveats with both Google TTS and Amazon Polly TTS, like the issue with In-Queue flows and agent whispers not working.

Subject: Google TTS - Speed & Pitch
Good afternoon all,
Apologies I have tried to search for this answer but was unable to locate anything. We are currently implementing Genesys Cloud and have leveraged the Google Cloud TTS to power our IVRs and other audio messages. However, I am shocked that there does not seem to be an obvious way to manipulate the playback as there is in other integrations... i.e - I would like to speed up the chosen voice engine, and pitch the tone of the vocals down slightly also. This usually helps with a more "realistic" feel to the voice.
I am new to Genesys and fairly new to Google Cloud TTS.
Am I missing something? Is there any way I can achieve this?
Many thanks,
