Microsoft releases Azure AI Speech LLM 2607 speech recognition model
Released the speech recognition model Azure AI Speech LLM 2607. The company claims it ranks 2nd on the HuggingFace OpenASR leaderboard and that latency is up to 3 times faster than the previous 2605 release. Mixed-language recognition, Tier 2/3 language support, and handling of capitalization, punctuation and number formatting were improved, and a phrase list that designates more than 2,000 entities as dedicated fields supports domain customization for corporate terms, product names and abbreviations. Says it is deployed automatically on the server side to both the Fast API and the Real-Time API, with no customer action needed. Pricing was not disclosed.
Why it matters
Shows that as ASR moves to LLM-based architectures, latency and customization of domain vocabulary, not just accuracy, have become competitive axes.
