GPT-Live-Transcribe is the streaming option for ongoing speech. It delivers low-latency transcript deltas from an audio stream and lets you tune latency. Unstructured context, keyword hints, and language hints help with domain terms and code-switching. Unlike GPT-Transcribe, the model is built around live speech rather than completed recordings.
GPT-Live-Transcribe returns text only even though input arrives as an audio stream. OpenAI bills it by audio minute; function calling and a ready-made voice agent are outside this transcription profile.

- Methodology
- Independent evaluation. Direct API streaming evaluation; final-transcription WER across AA-AgentTalk (50%), VoxPopuli (25%), and Earnings22 (25%), about eight hours total. WER is duration-weighted within dataset; Earnings22 chunking is reassembled at parent-call level. AA-WER v2.2 streaming protocol.
