A speech recognition technique is disclosed for recognizing words that are spoken at speeds that approach the speed of continuous speech. To avoid the cost of a rigorous approach wherein all possible words of stored vocabulary are correlated against each group of speech samples, this invention uses relatively long duration inter-string pauses to detect string boundaries, and relatively short duration inter-segment pauses to determine speech segment boundaries which are used as a limited number of start or end points.

Apparatus and method for recognizing spoken words

In this speech recognition system the array formed by a timewise sequence of speech signal feature vectors includes digital data at each time slot representing both presence/absence and consistency of occurence.
