Akopọ

XLS-R is a distinct cross-lingual model family built on the wav2vec 2.0 approach; its paper reports training on nearly half a million hours in 128 languages.

Jin Dive

Wav2Vec 2.0 uses a convolutional feature encoder and a Transformer context network. During pretraining, it masks latent spans and predicts quantized targets with a contrastive objective. The authors show fine-tuning can use relatively little transcribed speech in specified LibriSpeech experiments. XLS-R is a later cross-lingual model based on wav2vec 2.0; its paper reports models trained on nearly 500,000 hours of public speech across 128 languages. These results are specific to the published models and benchmarks.

In a reported LibriSpeech experiment, what small labeled-data setup demonstrated low-label potential?

The paper reports experiments using 10 minutes of labels after 53,000 hours of unlabeled pretraining; this is a specific benchmark setup, not a universal guarantee.
