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 .

Aura-2 Voice Controls , Speed and Pronunciation

Together, these controls give developers finer-grained tools to improve naturalness , tuning pacing and correcting pronunciation to match their needs.

These controls are also supported when using Aura-2 inside the Voice Agent API: set speed once at the session level, and have the LLM emit pronunciation overrides inline. See Voice Agent TTS Controls for the recommended setup.

These controls are powered by an updated Aura-2 voice-pack model. Self-hosted deployments using a voice-pack from before the April 2026 release will return 400 Bad Request on requests including speed or pronounce parameters. See the April 2026 self-hosted release notes for voice-pack version requirements and upgrade instructions.
