[Feature request] Tutorial should mention when to use Espeak (or Espeak-ng) and when to use Gruut phonemizer

[Ca-ressemble-a-du-fake]

🚀 Feature Description

It seems that the tutorial deals with Gruut ("If you use phonemes for training and your language is supported here, you don’t need to set your character list.") but some models provided with YourTTS contain Espeak as phonemizer (like the English one). By reading some comments here and there (discussion) some users even report using espeak-ng.

Solution

Tutorial should explain when to use one phonemizer over the other and what the differences in the config.json should be.

@p0p4k now that things are clearer, I will try and write something. According to @WeberJulian in gitter :

No it was for a time since phonemizer wasn't in a compatible licence But we wrote our own espeak wrapper Now it's supported and espeaker is prefered over gruut

So espeak should be used when training from scratch. When fine tuning a model (restore_path) or continuing a previous one (continue_path), then the same phonemizer than used in the original config.json has to be used.

[WeberJulian]

Yeah, you can also finetune from gruut to espeak. By default you should use espeak.
