If you want ML TTS, there are a lot of open source models out there, problem is most of them are trained on the same data, so your going to get similar voice options for the most part. You can definitely train your own text to speech, and pretty easily as well, but I'm assuming you don't want to go that route. Maybe try starting with Coqui TTS, but for reading long documents it definitely has its fair share of issues.
