I used Amazon Polly (text to speech engine) on a project a few years ago - the “neural” voices were decent. I’ve since heard much better synthetic voice engines, but don’t know names. What’s the best quality one you have found recently?
I haven't tried anything so far that I actually liked so my answer to "what's the best quality I have found?" is none.
The reverse though, OpenAI's Whisper for speech to text has been amazing, far exceeding my expectations.
Having just looked again I found a list at huggingface that I will be poking through in my spare time soon.
