Tree search strategy for large-vocabulary continuous speech recognition
Abstract
In this paper we describe a tree search strategy, called the Envelope Search, which is a time-asynchronous search scheme that combines aspects of the A* heuristic search algorithm with those of the time-synchronous Viterbi search algorithm. This search technique is used in the large-vocabulary continuous speech recognition system developed at the IBM Research Center.
