ABSTRACT:
In a speech signal recognition system, signals are data-reduced by eliminating highly-transient intervals: each successive time frame is temporarily identified as an anchor frame and compared to m preceding and m succeeding frames, whereby defined uniform time intervals of 2m+1 frames having a prescribed similarity are retained, and highly-transient 2m+1 intervals are discarded.
