How to upgrade to a supported streaming model

You’ll need to update your implementation to use one of our current streaming models. We recommend Universal-3 Pro Streaming (u3-rt-pro) as the primary streaming model. It delivers the highest accuracy with sub-300ms latency and native code switching across English, Spanish, German, French, Portuguese, and Italian.
  1. Review the Streaming documentation for model selection and implementation guidance.
  2. For a quick start guide, see our Getting Started with Streaming Audio documentation.
Universal-3 Pro Streaming and the Universal-Streaming family of models offer improved accuracy and reliability compared to our legacy streaming implementation.
