Fine-tuned
facebook/wav2vec2-large-xlsr-53 on French using the train and validation splits of
Common Voice 6.1.
When using this model, make sure that your speech input is sampled at 16kHz.
This model has been fine-tuned thanks to the GPU credits generously given by the
OVHcloud :)
The model can be used directly (without a language model) as follows...
