Lower is better on every measure. Too close to call means the likely ranges overlap.
Both providers, every model: Google vs Zoom
Google Chirp 3 and Zoom Scribe Pro are too close to call on accuracy. On the 1,000 public Pipecat clips, Google Chirp 3 scores 2.00% and Zoom Scribe Pro 1.96%, with likely ranges of 1.77 to 2.25% and 1.73 to 2.20%. The ranges overlap, so the difference is too close to call. On the eight licensed Ocular recordings, Google Chirp 3 scores 4.19% and Zoom Scribe Pro 4.84%, with likely ranges of 2.97 to 5.27% and 4.23 to 5.43%. The ranges overlap, so the difference is too close to call. Word error rate counts incorrect, missing, and extra words, so lower is better.

No. Zoom Scribe Pro finishes the transcript 313ms sooner. Google Chirp 3 has the final transcript 475ms after the speaker stops and Zoom Scribe Pro 162ms, at the median. Both are measured on the same 206 streamed turns.
Zoom Scribe Pro finishes the transcript 313ms 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.
Yes, both return partial text before the speaker stops. Google Chirp 3 shows first text after 4.48s and Zoom Scribe Pro after 1.70s, at the median, so Zoom Scribe Pro is 2.78s sooner.
