Whisper Large V3 Turbo - Fine-tuned for Canadian French (Québécois)

This is a fine-tuned version of openai/whisper-large-v3-turbo for Automatic Speech Recognition (ASR) on Canadian French (Québécois) speech.

It achieves a Word Error Rate (WER) of 6.65% on the validation set, offering significant improvements over the base model for the specific nuances, cadence, and vocabulary of Quebec French.

Model Details

Model Description

This model is fine-tuned from OpenAI's Whisper Large V3 Turbo. Unlike general French models, this version was trained on a mix of formal political speech and crowdsourced data to ensure robustness across different registers of Quebec French.

The training data includes the Assemblée Nationale du Québec (formal/political) and Common Voice (informal/diverse), making the model capable of handling both formal addresses and everyday accents.

• Model type: Sequence-to-sequence audio-to-text model (Whisper)
• Language(s): French (fr), specifically Canadian French (fr-CA)
• License: MIT
• Finetuned from model: openai/whisper-large-v3-turbo

How to Get Started with the Model

The model can be easily used with the pipeline from the 🤗 Transformers library.

from transformers import pipeline
import torch

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

pipe = pipeline(
  "automatic-speech-recognition",
  model="ele-sage/whisper-large-v3-turbo-fr-quebecois",
  device=device,
)

# Transcribe an audio file
audio_path = "path/to/your/audio.wav"
result = pipe(audio_path)

print(result["text"])

Uses

Direct Use

This model is intended for transcribing audio files containing Canadian French speech. It is particularly useful for:

• Transcribing Quebec media, podcasts, and interviews.
• Transcribing formal settings (political/legal) due to the inclusion of Assemblée Nationale data.
• General Canadian French ASR tasks where standard models struggle with the accent.

Training Details

Training Data

The model was fine-tuned on a total of approximately 69 hours of audio, combining three distinct datasets to balance specific dialect accuracy with general French capability:

1. Assemblée Nationale du Québec: ~13 hours (Formal, political context).
2. Common Voice (Français du Canada): ~16.5 hours (Native Quebecois accents).
3. Common Voice (Other French): ~39 hours (General French to prevent overfitting and maintain vocabulary coverage).

Training Procedure

Preprocessing

The raw audio was sampled at 16kHz. Audio clips longer than 30 seconds were excluded or segmented. SpecAugment was applied during training (masking time and frequency features) to provide data augmentation and combat overfitting.
