Abstract:
A method of assigning a penalty to a score in a voice recognition system comprising the steps of:generating at least one of:a lower threshold for the number of frames assigned to at least one state of at least one model;and an upper threshold for the number of frames assigned to at least one state of at least one model; andassigning at least one of:an out of state transition penalty to an out of state transition score in an allocation assignment algorithm, if the lower threshold has not been met, wherein the out of state transition penalty is proportional to the number of frames that a dwell time in the at least one state corresponding to the lower threshold is below the lower threshold;and a self loop penalty to a self loop score if the upper threshold number of frames assigned to a state has been exceeded, wherein the out of state transition penalty is proportional to the number of frames that a dwell time in the at least one state corresponding to the upper threshold is above the upper threshold.
