Speaker Identification Tools Compared
What it does, and how to check it yourself.
Speaker identification tools come in two kinds. Meeting apps such as Otter and Fireflies add names to your notes. APIs such as AssemblyAI, Deepgram and pyannoteAI return labels for developers to build on.
Checked November 2026 on each tool's own site. We ran no tests of our own.
How much do the API tools cost?
AssemblyAI lists speaker labels as an add-on from $0.02 an hour, and pyannoteAI's API starts at €19 a month.
