Audio2face integration with Riva TTS

I’m trying to follow this video which use Riva TTS extension to trigger face animation in Audio2Face. But instead of manually typing text in the RIVA TTS extension itself, I would like to invoke Riva TTS API to achieve the same outcome with streaming fashion, is it possible to do that?

I have setup Audio2Face and Riva service but have no idea how to move to the next step. Is there anyone who could provide some hints?

This is possible for ACE users. Please check this thread
