Fine-tuned whisper-large-v2 model for ASR in French
This model is a fine-tuned version of openai/whisper-large-v2, trained on the mozilla-foundation/common_voice_11_0 fr dataset. When using the model make sure that your speech input is also sampled at 16Khz. This model also predicts casing and punctuation.
Performance
Below are the WERs of the pre-trained models on the Common Voice 9.0, Multilingual LibriSpeech, Voxpopuli and Fleurs. These results are reported in the original paper.
| Model | Common Voice 9.0 | MLS | VoxPopuli | Fleurs |
|---|---|---|---|---|
| openai/whisper-small | 22.7 | 16.2 | 15.7 | 15.0 |
| openai/whisper-medium | 16.0 | 8.9 | 12.2 | 8.7 |
| openai/whisper-large | 14.7 | 8.9 | 11.0 | 7.7 |
| openai/whisper-large-v2 | 13.9 | 7.3 | 11.4 | 8.3 |
Below are the WERs of the fine-tuned models on the Common Voice 11.0, Multilingual LibriSpeech, Voxpopuli, and Fleurs. Note that these evaluation datasets have been filtered and preprocessed to only contain French alphabet characters and are removed of punctuation outside of apostrophe. The results in the table are reported as WER (greedy search) / WER (beam search with beam width 5).
