A voice recognition system (204, 206, 207, 208) assigns a penalty to a score in a voice recognition system. The system generates 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. The system assigns 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. The out of state transition penalty is proportional to the number of frames that the dwell time is below the lower threshold. A self loop penalty is applied to a self loop score if the upper threshold number of frames assigned to a state has been exceeded. The out of state transition penalty is proportional to the number of frames that the dwell time is above the upper threshold.
