Digital avatar integration with an existing conversational AI platform

Hi Team,
I am new to this community. I need some guidance on Nvidia products to start with integration with any Conversational AI platform such google dialog flow or kore.AI.
To Begin with, I need to integrate a voice based digital assistance (their own NLP engine and conversation logic flows) with Nvidia avatar and then host it locally.

Please help.
