Abstract
Continuous speech recognition is improved by use of a known vocabulary and context probabilities. First, the unknown utterance is analyzed as a sequence of phonemes, then each phoneme labelled to form a string of labels. The shortest label interval which is recognized as a word is assigned a storage stack where similar-sounding candidate words are stored. Multiple stack decoding, and liklihood envelope criteria for word path extension decisions, are further features of the system.
