Abstract :
A novel CMOS special-purpose LSI, the MSM6851, is described which realizes a voice-pattern-matching scheme for speaker-independent continuous voice recognition. A voice signal was specified by a specific pattern drawn on a plane with two axes: time axis and frequency axis. A simultaneous matching procedure on two axes was realized by a vector-processing LSI to absorb the difference of voice uttered by individual speakers. The vector-processing architecture was found to be essential for realizing the high-speed processing required by the proposed algorithm.<>
