Patent Images
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.

12. A method of correcting misrecognized speech continuous speech recognition system comprising the steps of:
-
a) affording a user a means to select a portion of a text representation of speech as being misrecognized; b) 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 as 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 uncharged; c) affording the user a means to select a portion of an alternative sequence; d) using a starting and a ending boundary of a selected portion of an alternative sequence to identify a portion of a selected portion of a text representation to be replaced; e) replacing said portion of the selected portion of a representation with a selected portion of an alternative sequence; f) identifying any remaining misrecognized speech; g) displaying a new list of alternative sequences for identified remaining misrecognized speech; h) affording the user a means to select an alternative sequence from said new list; and i) replacing said remaining misrecognized with a selected alternative sequence from the new list. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
