ABSTRACT:
A method and a system recognize speech based upon an approach which combines certain advantages of speech detection and word spotting for improved accuracy without sacrificing efficiency. The improved method and system is based upon the determination of a total similarity value based upon a cumulative value and power information at or substantially near a terminal frame.
