How to Test Speaker Accuracy
What it does, and how to check it yourself.
To test speaker accuracy, use one real meeting and write down who spoke when, for a few minutes of it. Then compare each tool's labels against your notes, and count how often the speaker is wrong.
Checked November 2026 on each tool's own site. We ran no tests of our own.
How long should the test recording be?
Ten to fifteen minutes is enough if it includes your usual number of speakers and some people talking over each other.
