Azure AI Speech LLM 2607 adds multilingual accuracy gains and phrase list customization

Microsoft released Azure AI Speech LLM 2607, which improves multilingual recognition, mixed-language audio handling, and domain-specific entity accuracy, and runs up to 3x faster than the previous 2605 release.

A new dedicated phrase list parameter lets developers supply domain vocabulary, supporting 2,000+ entities, without embedding it in a prompt.

The model is available through the Fast API and Real-Time API, is testable in the Foundry Playground, and is deployed automatically with no customer action required.
