Nova-3 vs Reson8 FAQ
Which is more accurate, Deepgram Nova-3 or Reson8?
Reson8 is more accurate on both datasets. On the 1,000 public Pipecat clips, Deepgram Nova-3 scores 3.78% and Reson8 2.38%, so Reson8 makes fewer errors by 1.40 points. On the eight licensed Ocular recordings, Deepgram Nova-3 scores 3.46% and Reson8 2.10%, so Reson8 makes fewer errors by 1.37 points. Word error rate counts incorrect, missing, and extra words, so lower is better.

Yes. Deepgram Nova-3 finishes the transcript 1.34s sooner. Deepgram Nova-3 has the final transcript 1.06s 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 Deepgram Nova-3 finishes the transcript 1.34s 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. Deepgram Nova-3 shows first text after 4.39% and Reson8 after 2.93%, at the median.
