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! 🚀

Speech-to-text is a solved problem until you actually try to build on it, then you realize accuracy on accented English, speaker diarization, and real-time latency are three completely different challenges. AssemblyAI quietly nails all three.

Exploring voice-based job interview prep features for Fillix - a Chrome extension that makes job hunting embarrassingly easy. The LLM gateway + transcription in one API call is exactly the kind of DX that makes a feature go from 'maybe someday' to 'shipping this week.
