Speaker diarization: getting Speaker 1 and Speaker 2 right

Identify speakers reliably in interviews, panels, and podcasts.

TL;DR

Use this lesson to identify speakers reliably in interviews, panels, and podcasts. Treat it as practical guidance, not a rigid rulebook.

Why it matters

Captions make clips understandable without sound, searchable after publishing, and reviewable by editors before export. The goal is to help you make a stronger clip without taking away your creative freedom.

What you will learn

Understand the caption or transcript decision behind this workflow.
Produce a usable transcript, caption file, or burned-in caption pass for one clip.
Catch the caption mistakes that most often hurt readability, accuracy, or platform fit.

Prerequisites

  • An audio file, video file, URL, or exported clip
  • A target output format such as SRT, VTT, burned-in MP4, or transcript text

What you need

A clip, audio file, transcript, or source URL.
A caption/transcription tool that can edit text and timing.
The target platform and caption delivery method.
A phone-size preview before export.

Core concept

Caption work is part accuracy and part design. The workflow only works if viewers can read the result quickly on a phone.

Example

Scenario

Auto-captions are mostly correct, but the clip contains names, numbers, jargon, or fast speech.

Move

Apply the workflow to a short section first and proofread the result at phone size.

Result

The caption pass becomes readable and accurate enough that sound-off viewers can follow the clip.

How to do it

  1. 1Use diarization when two or more speakers appear and captions or transcripts need correct speaker labels.
  2. 2Check the first speaker switch manually; early mistakes often repeat through the transcript.
  3. 3Rename generic labels like Speaker 1 and Speaker 2 once you know who is speaking.
  4. 4Correct crosstalk and short interjections manually because AI labels are weakest there.
  5. 5Do not show speaker labels in the final clip unless they help viewers follow the edit.

Expected output

A caption or transcript artifact that is proofread, timed, readable on a phone, and matched to the target platform.

Practice task

Produce a clean caption pass

  1. 1Take a 20-30 second section of a real clip.
  2. 2Apply the caption or transcript workflow from this lesson.
  3. 3Proofread it with sound on, then watch it again with sound off at phone size.

Check your work

Names, numbers, jargon, acronyms, and claims are correct.
Caption lines are short, timed well, and readable on a phone.
The final export uses the caption method the target platform will actually show.

Common mistakes and fixes

Do not finish Speaker diarization: getting Speaker 1 and Speaker 2 right without checking the exact words against the audio.
Do not let long caption blocks fill the screen on mobile.
Do not ignore names, numbers, acronyms, tickers, and niche terms.
Do not assume every platform will show sidecar caption files.
Do not export before checking caption placement at phone size.

Troubleshooting

If captions are too dense, split or rewrite into shorter one- or two-line blocks.
If caption timing drifts, fix timing after the final edit rather than before.
If platform captions and burned-in captions clash, choose one caption strategy for that upload.
