Voice models/training

[JuniorGamingTime]

So I have MeloTTS running on a docker faster than real time (GPU) and a FastAPI wrapper. But was wondering are there any other pre train models to use? I want to be able to change the voice to a male.

Also for training my own model how much data do I need? And when getting the training data should only include the voice of how I want the end model to sound like?

Never done anything like this, so I bit lost!
