Learn more about our flagship model: Blizzard
Blizzard, our default model, is a powerful and expressive text-to-speech model that delivers natural, high-quality voice synthesis with excellent prosody and emotional range.
Note: The Aurora model ID (
aurora
) is now an alias that routes all requests to Blizzard. As Blizzard has reached production maturity, we’ve consolidated our model offering to provide a single, high-performance solution. This change ensures consistent quality and reliability across all voice synthesis requests.
Models receive regular updates and improvements. Most updates are non-breaking and require no changes to your applications.
When we need to make breaking changes:
You can find which specific model version handled your request in the API response headers under X-Model-Version
. We recommend logging this value for debugging.
We’ll notify you about model updates, breaking changes, and deprecation windows through these channels.
