Question
How Fireflies Speaker Diarization Works
What it does, and how to check it yourself.
Fireflies tells speakers apart by their voices, and it uses its meeting bot to match those voices to names. That is why the same recording without the bot shows only Speaker 1 and Speaker 2.
Checked November 2026 on each tool's own site. We ran no tests of our own.
Does Fireflies work with an uploaded file?
Yes. Its pricing page lists uploads of audio and video files. Check the names in the transcript, because no bot was in the meeting.
