For many practicalapplicationsof speechrecognitionsystems, it is quitedesirableto have anestimateof confidencefor eachhypothesizedword. Unlike previousworkson confidencemeasures, we have proposedfeaturesfor confidencemeasuresthatareextracted from outputsof more than one LVCSR models.For furtheranalysisof theproposedconfidencemeasure, this paperexaminesthe correlationbetweeneachword’s confidenceand the word’s featuressuchasits part-of-speechandsyllablelength.Wethenapply SVM learningtechniqueto… CONTINUE READING
