A CMOS integrated array processor for computing the dynamic time warp algorithm is described. It allows many popular variations including LPC and frequency domain representations of speech. High speed is obtained by extensive pipelining, parallel computation, and simultaneous matching of multiple patterns. A realistic application using 40 nine-component LPC vectors per word permits 10,000 word comparisons per second or, equivalently, real time recognition of a 10,000 word vocabulary.
