Whisper is a pre-trained model for automatic speech recognition (ASR) and speech translation. Trained on 680k hours of labelled data, Whisper models demonstrate a strong ability to generalise to many datasets and domains without the need for fine-tuning.
This int8 ONNX model is generated by neural-compressor and the fp32 model can be exported with below command:
optimum-cli export onnx --model openai/whisper-large whisper-large-with-past/ --task automatic-speech-recognition-with-past --opset 13

Intended Use | Description |
---|---|
Primary intended uses | You can use the raw model for automatic speech recognition inference |
Primary intended users | Anyone doing automatic speech recognition inference |
Out-of-scope uses | This model in most cases will need to be fine-tuned for your particular task. The model should not be used to intentionally create hostile or alienating environments for people. |
