WMT21 Marian translation model (ca-oc multi-task)

This is a neural machine translation model for Catalan to Occitan translation. It is a multi-task model, also producing phonemic transcription of the Catalan source. The model was submitted to [WMT21 Multilingual Low-Resource Translation for Indo-European Languages Shared Task](https://www.statmt.org/wmt21/multilingualHeritage-translation-task.html) as a CUNI-Contrastive system for Catalan to Occitan.
The model is available for download from the LINDAT repository.
