Abstract
An automatic speech recognition system employs parallel syntaxes with a first syntax operative to compare keyword templates with incoming speech over a given time interval and with a second syntax in parallel with the first and operative to compare filler templates with incoming speech over the same interval. Based on the best comparisons in each syntax a likelihood probability ratio is computed and compared against a selected threshold for determining whether the speech contains a valid phrase or keyword as compared to an undesirable utterance.
