French Medium Whisper

This model is a fine-tuned version of openai/whisper-medium on the common_voice_11_0 dataset. It achieves the following results on the evaluation set:

  • Loss: 0.2664
  • Wer (without normalization): 15.8969
  • Wer (with normalization): 11.1406

New SOTA

The Normalized WER in the OpenAI Whisper article with the Common Voice 9.0 test dataset is 16.0.

As this test dataset is similar to the Common Voice 11.0 test dataset used to evaluate our model (WER and WER Norm), it means that our French Medium Whisper is better than the Medium Whisper model at transcribing audios French in text.
