Why teams pick PyAI over Deepgram
Telephony-native transcription, with a clean path to live agents.
Tuned for 8 kHz call audio
Transcription built for narrowband phone lines, not podcast studios - accuracy holds up where real calls actually happen.
Eager streaming partials (~200 ms, in-region)
A ~200 ms first partial (in-region, revisable) plus a final per utterance lets you barge-in, endpoint, and react mid-sentence instead of waiting for the end.
OpenAI-compatible drop-in
Point your existing OpenAI client at PyAI and change two lines - the request and response shapes match.
Grows into the full agent
Start with transcription, then add grounded turn-taking and end-to-end Omni agents on the same account when you're ready.
