Fine-tuned whisper-small model for ASR in French

This model is a fine-tuned version of openai/whisper-small, 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).

Model	Common Voice 11.0	MLS	VoxPopuli	Fleurs
bofenghuang/whisper-small-cv11-french	11.76 / 10.99	9.65 / 8.91	14.45 / 13.66	10.76 / 9.83
bofenghuang/whisper-medium-cv11-french	9.03 / 8.54	6.34 / 5.86	11.64 / 11.35	7.13 / 6.85
bofenghuang/whisper-medium-french	9.03 / 8.73	4.60 / 4.44	9.53 / 9.46	6.33 / 5.94
bofenghuang/whisper-large-v2-cv11-french	8.05 / 7.67	5.56 / 5.28	11.50 / 10.69	5.42 / 5.05

Usage

Inference with 🤗 Pipeline

python

import torch

from datasets import load_dataset
from transformers import pipeline

device = torch.device("cuda:0" if torch.cuda.is_available() else "cpu")

# Load pipeline
pipe = pipeline("automatic-speech-recognition", model="bofenghuang/whisper-small-cv11-french", device=device)

# NB: set forced_decoder_ids for generation utils
pipe.model.config.forced_decoder_ids = pipe.tokenizer.get_decoder_prompt_ids(language="fr", task="transcribe")

# Load data
ds_mcv_test = load_dataset("mozilla-foundation/common_voice_11_0", "fr", split="test", streaming=True)
test_segment = next(iter(ds_mcv_test))
waveform = test_segment["audio"]

# Run
generated_sentences = pipe(waveform, max_new_tokens=225)["text"]  # greedy
# generated_sentences = pipe(waveform, max_new_tokens=225, generate_kwargs={"num_beams": 5})["text"]  # beam search

# Normalise predicted sentences if necessary
