CONTINUOUS SPEECH RECOGNITION SYSTEM

摘要

PIRZ, F. C. 5-11 CONTINUOUS SPEECH RECOGNITION SYSTEM A continuous speech analyzer is adapted to recognize an utterance as a series of reference words for which acoustic feature signals are stored. Responsive to the utterance and reference word acoustic features at least one reference word series is generated as a candidate for the utterance. Successive word positions for the utterance are identified. In each word position, partial candidate series are generated by determining reference word corresponding utterance segments and combining reference words having a prescribed similarity to their utterance segments with the partial candidate series of the preceding word position. The determined utterance segments have beginning points within a predetermined range of the utterance position endpoint for the preceding word position candidate series to account for coarticulation and differences between acoustic features of the utterance and those for reference words spoken in isolation.
