The Complete Guide to Punctuation & Capitalization in Speech-to-Text

The Complete Guide to Punctuation & Capitalization in Speech-to-Text discusses how automatic speech recognition (ASR) can be tricky for punctuation and capitalization, especially across different languages. It explains the purpose of punctuation and its role in making a text more understandable by providing some sense of intonation and pacing that would occur if a sentence was spoken out loud. Capitalization is also discussed as the process of making a letter capital or upper case, with proper nouns being typically capitalized in English. The importance of punctuation and capitalization for speech recognition is highlighted, as they make texts clearer and easier to read by humans. Two methods of adding punctuation to ASR transcripts are presented: a separate punctuation and capitalization model that runs after the text has been generated, and an end-to-end deep learning system that generates both text and punctuation simultaneously, using acoustic information for better accuracy.
