OpenAI's open-source speech recognition model for transcription, translation and language ID
One Transformer handles transcription, speech translation into English, language identification and voice activity detection, selected through special task tokens.
Choose from tiny, base, small, medium, large and turbo checkpoints, with English-only .en variants, to balance accuracy against VRAM and speed.
Multilingual checkpoints transcribe and translate dozens of languages, with automatic language detection on mixed-language audio.
Install via pip with openai-whisper and transcribe files from the terminal or from your own Python code, with ffmpeg handling audio decoding.
