Model description

Homepage: SIL AI
Point of Contact: SIL AI email
Source Data: Bloom Library

This model is a fine-tuned version of facebook/wav2vec2-xls-r-300m on the SIL-AI/bloom-speech SDK (Sos Kundi) dataset. It achieves the following results on the evaluation set:

Loss: 0.6454
Wer: 0.3878
Cer: 0.0925

Users should refer to the original model for tutorials on using a trained model for inference.

Intended uses & limitations
