Aura-2 Speed and Pronunciation Controls require an updated voice-pack

The new Aura-2 Speed and Pronunciation Control features in this release are powered by an updated Aura-2 English voice-pack model. If your deployment is using an Aura-2 English voice-pack from before the April 2026 release (e.g., the 2025-04-15.0 version of the voice-pack), requests including the speed or pronounce parameters will return 400 Bad Request.

To enable these features, contact your Deepgram representative to obtain the latest Aura-2 English voice-pack (2025-04-15.4 or later) and replace the existing voice-pack file in your models directory. The official Deepgram Helm chart and sample values files in deepgram/self-hosted-resources (chart 0.34.0 and later) already point to the correct UUID; you only need to use the latest Deepgram configuration files and update the model file on disk.
