Training on a different language

[OSSome01]

First of all thanks for the wonderful work guys!
I had a couple of doubts regarding training mellotron on languages other than English.
I am new to this domain so forgive me if these are stupid questions

1. Can I train mellotron on the "Hindi" language? It is based on the "Devnagari" script.
2. The research paper mentions that we requires text, audio files and speaker ids. I have a dataset available, but it is in the devnagari script, so I was doubtful it would work out of the box. I think I'll have to transliterate the input text. Is there any other way to do it?
3. Also for inference how will I be able to get the rhythm of the source.

Thanks!!

Also approximately how much audio data is required to get good results?
