 Model Description
 -----------------
 In addition to `Punctuation And Capitalization model <https://docs.nvidia.com/deeplearning/nemo/user-guide/docs/en/main/nlp/punctuation_and_capitalization.html>`_ we add audio encoder (e.g. Conformer's encoder) and attention based fusion of lexical and audio features.
