Riva 1.0 Beta: What’s New
Riva 1.0 Beta includes fully optimized pipelines for deploying real-time conversational AI applications such as transcription, virtual assistants and chatbots.
Highlights:
- Automatic speech recognition (ASR), natural language understanding (NLU), and text-to-speech (TTS) models in the NVIDIA NGC™ catalog trained on thousands of hours of speech data
- Integration with the NVIDIA TAO Toolkit to re-train on custom data
- Fully accelerated deep learning pipelines optimized to run as scalable services
- End-to-end workflow and tools to deploy services using one line of code

Build Real-Time Apps with Riva Services
NVIDIA’s platforms and application frameworks enable developers to build a wide array of AI applications. Consider potential algorithmic bias when choosing or creating the models being deployed. Work with the model’s developer to ensure that it meets the requirements for the relevant industry and use case; that the necessary instruction and documentation are provided to understand error rates, confidence intervals, and results; and that the model is being used under the conditions and in the manner intended.
