A device (100) including a voice recognition system (204, 206, 207, 208) that generates a signal representative of the speech utterance. The utterance is divided into frames (Ft) representative of the utterance. Frames are allocated to states (S1-S5) using an alignment algorithm. A path representing frame to state allocations is stored in memory (110) using state transition types identifying a state transition to each state. Lattice traceback information for the voice recognition system is stored and updated by generating a traceback array having a plurality of rows and one or more columns, with each row of the plurality of rows corresponding to one of a plurality of states in which a traceback path terminates, and each column containing one or more dwell counts for states in the traceback path. An optimal state transition path into a given state of the plurality of states is determined, and the generated traceback array is updated in response to the determined optimal state transition path. |
