What Is Whisper
Whisper is OpenAI’s open-source automatic speech recognition model. It transcribes audio to text — and can translate it — with strong accuracy across languages, accents, and background noise.
In Practice
Because Whisper is open source, it powers a huge range of transcription tools, subtitle generators, and voice interfaces. Developers self-host it for cost control and privacy, or call it through OpenAI’s API for convenience.
