Paper Abstract

Optical spectrographic processing systems have been shown to be the most widely used techniques for time-varying signals that usually contain very distinct characteristics in spectral distributions and are difficult to categorize in time (spatial) domain. In this paper, an optical architecture for spectrograph generation, by which time-varying signal processing can be performed, is proposed and its implementation is described in detail. Some potential applications using optical spectrographic processing system in phonetics, linguistics, speech identification are investigated. Simulation results are also presented to demonstrate the effectiveness of the optical spectrographic processing system in those application areas. Other applications of the optical spectrographic analysis system in identifying individuals through "voice prints" or in detecting mechanical fatigue through abnormal noise are also indicated.
