Patent ID: 7996218

Claim:
A user adaptive speech recognition method comprising: calculating confidence scores of respective recognition candidates according to results of speech recognition of respective user input speech; setting a new threshold value adapted to one or more users based on results of respective user confirmations by the one or more users of the respective recognition candidates according to a previous threshold value, wherein the setting of the new threshold value includes selectively setting the new threshold value so as to have a value according to a select range, selected from plural ranges differently defining respective ranges, based upon a determination indicating that a first confidence score of a first recognition candidate, that should be rejected, is greater than a confidence score of a second recognition candidate, that should be accepted, or a confidence score of a third recognition candidate, that should be accepted, is less than a confidence score of a fourth recognition candidate, that should be rejected; and outputting a corresponding recognition candidate as a result of the speech recognition when a calculated confidence score of the corresponding recognition candidate is determined to meet the new threshold value.
