# Massively Multilingual Speech (MMS) - Common Crawl Language Models

This repository consists of the n-gram language models trained on Common Crawl data ([Conneau et al. 2020b](https://aclanthology.org/2020.acl-main.747/), [NLLB_Team et al. 2022](https://arxiv.org/abs/2207.04672)) using [KenLM library](https://github.com/kpu/kenlm). 


For the following languages, the LMs are not present in the repository (due to 50GB limit on HuggingFace) and can be downloaded using the link provided here. 

Mandarin Chinese (Simplified) - [Download LM](https://dl.fbaipublicfiles.com/mms/lms/cmn-script_simplified/char_20gram.bin)
