Speaker recognition
Transcripts that know who said what
NoteOwl gives you transcription with speaker identification on your Mac: every line of a meeting transcript says who said it and when, and you can play any line to hear it again.
Name a speaker once and NoteOwl recognises that voice in later meetings; the voice profile stays on your Mac, and speaker labels come with NoteOwl Pro.
Read the transcript
Your transcript says Speaker 3 will send the checklist by Friday. So… who’s Speaker 3?
This is NoteOwl. It takes notes on your calls, right on your Mac, and labels every line with who said it.
Name a voice once. Every line updates, and NoteOwl learns her voice. On your Mac, nowhere else.
Now open another meeting she was in. NoteOwl already knows that voice.
There she is. Priya’s sending the checklist.

How does speaker identification work in NoteOwl?
When a meeting ends, NoteOwl separates the voices and labels every line of the transcript with who said it. Your microphone is you; everyone else on the call is split out from your Mac’s audio. Name a speaker once, and later meetings label them for you.
- 1
Record or import
Record a call from your Mac with no bot joining it, or import an audio or video file.
- 2
The voices are separated
When the call ends, NoteOwl splits the other people on it into separate speakers; your microphone is always You. An import is labelled right after its transcript appears.
- 3
Name them once
Click Rename speakers above the transcript, type real names and click Save. Every line updates at once.
- 4
Recognised next time
NoteOwl learns each voice you name. When a later meeting ends, it compares the voices it separated with them and fills in the names.

What is speaker diarization?
Speaker diarization is splitting a recording by who is speaking, answering “who spoke when” before anyone’s name is known. NoteOwl runs it on your Mac for meetings and imports; speaker recognition then puts real names on the voices you have named.
More plain definitions, from speaker diarization to SRT files, are in the NoteOwl glossary.

Yours to correct
Wrong number of speakers
Open Identify Speakers under the meeting’s title and choose how many people spoke, from 2 to 8, or Automatic. NoteOwl separates the voices again and keeps that count.
One person split in two
Give both speakers the same name and they become one. NoteOwl never learns a voice from a merge, so two people can’t blend into one voice profile.
A line under the wrong name
In an imported transcript, right-click the line and choose Assign to.
Hear it again
Press play beside any line to hear exactly what was said, in that person’s voice.
Copy with names
Copy puts the whole transcript on your clipboard with every speaker’s name and time.
Does NoteOwl recognise voices in later meetings?
Yes, once you name them. NoteOwl keeps a voice profile for everyone you name; when a later meeting ends, it compares each voice it separated with those profiles and fills in the names. The person’s profile in People shows the voice as recognised.
Every named voice belongs to a profile in the personal CRM NoteOwl builds from your meetings, with what’s still open between you.

Where are voice profiles stored?
Only on your Mac. NoteOwl builds each voice profile on your Mac and never uploads it. Forget on the person’s profile removes it, and Export all data leaves voice profiles out unless you tick them, because it marks them Sensitive.
NoteOwl records the call itself, as an AI note taker without a bot, so the speakers are separated on your Mac too. Speaker labels and voice recognition are part of NoteOwl Pro; dictation and voice notes are free.
