wav2vec2-xls-r-300m-hebrew

This model is a fine-tuned version of facebook/wav2vec2-xls-r-300m on the private datasets in 2 stages - firstly was fine-tuned on a small dataset with good samples Then the obtained model was fine-tuned on a large dataset with the small good dataset, with various samples from different sources, and with an unlabeled dataset that was weakly labeled using a previously trained model.

Small dataset:

split size(gb) n_samples duration(hrs)
train 4.19 20306 28
dev 1.05 5076 7

Large dataset:

split size(gb) n_samples duration(hrs)
train 12.3 90777 69
dev 2.39 20246 14*
(*weakly labeled data wasn't used in validation set)

After firts training it achieves:

on small dataset

  • Loss: 0.5438
  • WER: 0.1773

on large dataset

  • WER: 0.3811

after second training: on small dataset

  • WER: 0.1697

on large dataset

  • Loss: 0.4502
  • WER: 0.2318
