OpenAI's Whisper Model Explained

3-Second Blueprint (English)

1. Whisper splits audio into 30-second segments processed through an encoder-decoder Transformer with cross-attention.
2. Weakly supervised training on 600,000+ hours of multilingual web audio yields near-human robustness to noise.
3. Open model weights let developers fine-tune Whisper as a speech foundation model for domain-specific accuracy.
