Overview of Whisper
Whisper is an advanced AI speech recognition model developed by OpenAI. It is trained on 680,000 hours of multilingual and multitask supervised data, enabling it to perform multilingual speech recognition, speech translation, and spoken language identification. The model is based on a sequence-to-sequence architecture, allowing for joint representation of sequence tokens and prediction decoding. Whisper offers five available model sizes with varying speed and accuracy tradeoffs, and it is open-source under the MIT license.
How Does Whisper Work?
Whisper utilizes a large and diverse dataset to achieve improved robustness to accents, background noise, and technical language. It is implemented as an encoder-decoder Transformer, where input audio is split into 30-second chunks, converted into a log-Mel spectrogram, and then passed into an encoder. A decoder is trained to predict the corresponding text.
