ABSTRACT:
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.
