Abstract
A system for recognizing speech based on an input data stream indicative of the speech provides possible words represented by the input data stream as a prefix tree including a plurality of phoneme branches connected at nodes. The plurality of phoneme branches is bracketed by at least one input silence branch corresponding to a silence phone on an input side of the prefix tree and at least one output silence branch corresponding to a silence phone on an output side of the prefix tree. The prefix tree is traversed to obtain a word that is likely represented by the input data stream. The silence phones provided in the prefix tree can vary based on context.
