Abstract
In a speech recognition system which recognizes a spoken utterance consisting of a sequence of spoken words and, in response, outputs a sequence of decoded words, a method for automatically punctuating the sequence of decoded words is provided. In a vocabulary of items including words, silences, and punctuation marks, assigning at least one baseform to each punctuation mark corresponding to one of silence and a non-word noise. Additionally, the method includes the step of automatically inserting a subject punctuation mark at a given point in the sequence of decoded words when an acoustic score and a language model score associated with the subject punctuation mark produce a higher combined likelihood than the acoustic score and the language model score associated with any other item in the vocabulary for the given point in the sequence of decoded words.
