Hey PH 👋 We just shipped the most accurate real-time STT model for voice agents.
Universal-3 Pro Streaming is a first-of-its-kind realtime Speech Language Model built for the hard stuff voice agents actually encounter (disfluencies, emails, URLs, names, account numbers, alphanumerics, and code-switching across languages). All in noisy conditions. All at super low latency.
Here's what we kept seeing: incorrect credit card numbers. Turn detection cutting off customers mid-sentence. Speaker labels scrambled in multi-party calls. Voice agent failures cluster around the edge cases that matter most to your users. Existing streaming models weren't solving them.
So we took every capability from Universal-3 Pro and brought it to real-time streaming. Plus two new capabilities that didn't exist in streaming before: real-time speaker diarization and global language support through the same API.
We'd love to see what you build with it! 🚀
