Overview

NVIDIA’s intelligent virtual assistant AI solution workflow integrates NVIDIA Riva English automatic speech recognition (ASR) and text-to-speech (TTS) with Haystack, a third-party, open-source natural language processing (NLP) service for information retrieval and question answering (IRQA), and Rasa, an open-source dialog manager.

Example training and inferencing pipelines are built using Riva, Haystack, and Rasa, to demonstrate how to customize and build a virtual assistant solution for a specific use case, in this case financial services. Additional supporting components are also integrated as shown in the below diagram.

The packaged components of this workflow are cloud native and include examples of enterprise-ready best practices for authentication, monitoring, reporting, and load balancing, while allowing a path to deviate.
