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
