Adding support for F5-small models, sharing a Hindi checkpoint trained from scratch and adding NFE steps in inference scripts

In this PR I am contributing three things as given in title.

Oh hindi is nice how much hour you train model , becuas im train 60H and is not result like your's model and wht setting

I have trained the small config model with about 80 hrs of data for 2.5 million steps.

Thanks a lot!
Will check after #518 , which enables using yaml for better config

@rumourscape Hi, Can you share training code for this model?

[justinjohn0306]

I tested the model and it sounds trash

actually is better compare to 80H of training

You clearly haven't used it properly then. The ref_audio must be in Hindi and the ref_text & gen_text must be in Devanagari script. I have showed this model to many colleagues and they all believe that this is probably the current SOTA for Hindi TTS.

@rumourscape Hi, Can you share training code for this model?

I have used the same training script as given in the F5 repo. The only change I made was to skip the preprocess step and directly plug in the Huggingface datasets using the HFDataset class.
PS: I also avoided the convert_char_to_pinyin function to prevent extra spaces in between characters.

That's a good change to add upstream. Would make it much easier to train on other languages.

@SWivid @ZhikangNiu Hi, are you looking into this?

[SWivid]

@rumourscape yes, but busy currently, will modified as mentioned in #591
will come back and add this feature asap

It would be great if you add Hindi language support. Thank you in advance.
