Azure AI Speech LLM 09-2026 expands transcription with 25 additional languages, including 11 Indic languages, bringing coverage to 50 languages and more than 60 locales.
Microsoft reports processing up to twice as fast as version 2607, particularly for short audio at high concurrency, alongside recognition and silence-handling improvements.
The model is available through the Fast Transcription API and is deployed automatically on the service side. Voice-agent, captioning and contact-center developers can use REST, SDK or Foundry Playground access.
