[TTS] Riva support Fastpitch + GST (global style token) model?

I want to train 1 model Nemo TTS Fastpitch + GST. I don’t know if Riva supports this model or not?

I found this model code on the fastpitch gst branch on the Nemo github that the team developed GitHub - NVIDIA/NeMo at fastpitch_gst. Can I training model using this code?

Thanks!

Hi @user63286

Thanks for your interest in Riva

I will check with my team and let you know

Currently for custom models, we support
FastPitch + HiFi-GAN IPA
FastPitch + HiFi-GAN ARPABET
FastPitch + HiFi-GAN LJSpeech

Please find the reference link below

Thanks

HI @user63286

I have inputs from the internal team

That branch is out-dated. The most up-to-date version of the work linked is https://github.com/NVIDIA/NeMo/pull/5499.

The Team is internally evaluating it, but we have no timeline or commitment on adding it to Riva at the moment.

Thanks
