Transcription Accuracy Compared
What it does, and how to check it yourself.
No independent test ranks Otter, Fireflies and Whisper on the same audio, so no one can name the most accurate. Your microphones, noise and accents change the result more than the choice of tool in most meetings.
Checked November 2026 on each tool's own site. We ran no tests of our own.
What is Whisper?
Whisper is an open-source speech recognition model from OpenAI. You run it yourself, or use it through another product. It is not a meeting app.
