Frequently Asked Questions

What is OpenAI Whisper?

Whisper is OpenAI's open-source speech recognition model. Released in 2022, it transcribes audio in 100+ languages with high accuracy. It's a developer tool — not a consumer app — that runs locally or via API. Many transcription apps are built on top of Whisper.

Is Whisper free?

Whisper is completely free and open-source. You can download and run it locally at no cost. OpenAI also offers Whisper via its API at $0.006 per minute. Consumer apps built on Whisper (like many transcription tools) typically charge their own subscription fees.

Is Otter.ai built on Whisper?

Otter.ai uses its own proprietary speech recognition technology, not Whisper. Many newer transcription tools use Whisper under the hood, but Otter.ai has built its own ASR (automatic speech recognition) system optimized for meetings and conversations.

Which is more accurate — Whisper or Otter.ai?

Whisper (especially the large model) is among the most accurate general-purpose speech recognition systems available. Otter.ai is optimized for meeting conversations and performs well for that specific use case. For general transcription of diverse audio, Whisper's accuracy is excellent. For live meeting intelligence with integrations, Otter.ai has practical advantages.
