+# XLS-R-based CTC model with 5-gram language model from Common Voice
 
-This model is a version of [facebook/wav2vec2-xls-r-2b-22-to-16](https://huggingface.co/facebook/wav2vec2-xls-r-2b-22-to-16) fine-tuned mainly on the MOZILLA-FOUNDATION/COMMON_VOICE_8_0 - NL dataset (see details below).
-It achieves the following results on the evaluation set (of Common Voice 8.0):

 ## Model description
 
-The model takes 16kHz sound input, and uses a Wav2Vec2ForCTC decoder with 48 letters to output the final result.
