1. A continuous speech recognition apparatus, comprising: a memory storing an LR table; a prediction LR parser using an action specification item from the stored LR table for predicting a phoneme; phoneme context predicting means for predicting a phoneme context in the vicinity of the phoneme predicted by said prediction LR parser using an action specification item from the stored LR table; a memory storing context dependent HMM data characterizing a plurality of types of phonemes which may be found in speech; and phoneme verifying means, responsive to an input speech signal, for verifying existence of the predicted phoneme by using context dependent HMM data corresponding to the predicted phoneme context to determine the probability that the predicted phoneme exists in the input speech signal, wherein each time that the phoneme verifying means verifies existence of a phoneme, the verified phoneme is applied to the prediction LR parser such that the prediction LR parser predicts a succeeding phoneme, the phoneme context predicting means predicts a phoneme context in the vicinity of the predicted succeeding phoneme, and the phoneme verifying means uses context dependent HMM data corresponding to the predicted phoneme context in the vicinity of the predicted succeeding phoneme to determine the probability that the predict succeeding phoneme exists in the input speech signal, whereby the continuous speech recognition apparatus develops a symbol string based on a series of verified phonemes representing a sentence or phrase.
