Show all 24 claims
Having thus described our invention, what we claim as new and desire to secure by Letters Patent is as follows:     1. A method of correcting incorrectly decoded speech in a continuous speech recognition system comprising the steps of:
  • affording a user a means to select a portion of text representation of the speech as being misrecognized;
  • displaying a list of a multiplicity of likely alternative sequences of words to the user, wherein the list of alternative sequences is generated by including at least a word preceding said selected portion of text and/or at least a word following said selected portion of text and by decoding an interval of user speech under a constraint that a decoding of either and/or both a preceding or a following word remains unchanged;
  • affording the user a means to select an alternative sequence;
  • replacing the selected portion of text representation with a selected alternative sequence.
