No. Reson8 finishes the transcript 395ms sooner. GPT-4o Mini Transcribe has the final transcript 630ms after the speaker stops and Reson8 235ms, at the median. Both are measured on the same 206 streamed turns.
Reson8 finishes the transcript 395ms sooner, and the two are too close to call on real conversations. A voice agent cannot reply until the final transcript arrives, and the Ocular recordings are real conversations.
Only Reson8. GPT-4o Mini Transcribe returns no text until the speaker stops, which matters if your agent reacts to partial transcripts.
