Abstract:     A method of identifying homophones of a word uttered by a user from at least a portion of existing words of a vocabulary of a speech recognition engine comprises the steps of: a user uttering the word; decoding the uttered word; computing respective measures between the decoded word and at least a portion of the other existing vocabulary words, the respective measures indicative of acoustic similarity between the word and the at least a portion of other existing words; if at least one measure is within a threshold range, indicating, to the user, results associated with the at least one measure, the results preferably including the decoded word and the other existing vocabulary word associated with the at least one measure; and the user preferably making a selection depending on the word the user intended to utter.

Show all 39 claims
What is claimed is:     1. A method of identifying homophones of a word uttered by a user from at least a portion of existing words of a vocabulary of a speech recognition engine, the method comprising the steps of:
  • decoding the uttered word using the speech recognition engine to yield a decoded word;
  • computing respective measures between the decoded word and at least a portion of the other existing vocabulary words, the respective measures indicative of acoustic similarity between the word and the other existing words;
  • identifying the other existing words, associated with measures which correspond to a threshold range, as homophones of the uttered word; and
  • outputting the identified homophones, wherein the user can select an identified homophone that corresponds to the word uttered by the user.
