For documentation on previous versions or features not yet available in 2.0, please refer to the NeMo 24.07 documentation.

Punctuation And Capitalization Models

Automatic Speech Recognition (ASR) systems typically generate text with no punctuation and capitalization of the words. There are two issues with non-punctuated ASR output:

• it could be difficult to read and understand

• models for some downstream tasks, such as named entity recognition, machine translation, or text-to-speech synthesis, are usually trained on punctuated datasets and using raw ASR output as the input to these models could deteriorate their performance

NeMo provides two types of Punctuation And Capitalization Models:

Lexical only model:

• Punctuation and Capitalization Model

Lexical and audio model:
