Yes. Gradium finishes the transcript 695ms sooner. Gradium has the final transcript 1.71s after the speaker stops and Reson8 2.40s, at the median. Both are measured on the same 206 streamed turns.
It is a trade-off. Reson8 makes fewer errors on real conversations, while Gradium finishes the transcript 695ms sooner. A voice agent cannot reply until the final transcript arrives, and the Ocular recordings are real conversations.
Yes, both return partial text before the speaker stops. Gradium shows first text after 4.45% and Reson8 after 2.93%, at the median.
