Abstract: 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.

Abstract translation: 一种包括语音识别系统（204,206,207,208）的设备（100），其产生代表语音话语的信号。 话语被分为表示话语的帧（Ft）。 使用对准算法将帧分配给状态（S1-S5）。 表示帧到状态分配的路径使用标识到每个状态的状态转换的状态转换类型来存储在存储器（110）中。 通过生成具有多个行和一个或多个列的追溯阵列来存储和更新用于语音识别系统的格子回溯信息，其中多个行中的每一行对应于回溯路径终止的多个状态之一 ，并且每列包含用于回溯路径中的状态的一个或多个驻留计数。 确定进入多个状态的给定状态的最佳状态转换路径，并且响应于所确定的最佳状态转换路径来更新生成的追溯阵列。
