Whisper

Overview

Whisper is an open-source speech recognition model released by OpenAI. It transcribes audio in many languages, can translate speech into English, and produces timestamps that help you align text with a recording. Because the model can be downloaded and run on your own hardware, it is widely used by developers, researchers and creators who want transcription without sending audio to a third-party service. Running it locally takes some setup, and the larger models need a capable GPU to run at a reasonable speed on large files. Like other speech models, it can produce errors on noisy audio, strong accents or poor recordings, and it has been known to generate text during silence. Review transcripts before relying on them for legal, medical or published material.
