Transcribing speech on infrastructure you control
Whisper provides downloadable speech-recognition models for transcription, language identification, translation into English, and caption-making without requiring a hosted speech service.
- AI’s role
- A multilingual sequence-to-sequence model converts audio into timestamped text or translated text.
- Documented result
- OpenAI released model weights, inference code, and a command-line interface under MIT terms in September 2022, making local runs broadly reproducible.
- Important limitation
- Accuracy varies with language, accent, noise, recording conditions, and subject matter. The training corpus and a complete training recipe were not released.
