Abstract
A white-light optical processing technique of generating speech spectrogram is presented. The speech spectrograms thus generated are frequency color-coded resulting in easier visual discrimination. The temporal-to-spatial conversion of speech signal is accomplished by means of density modulation with a CRT scanner. The scaling procedure of the speech spectrogram as well as the frequency resolution limit of the system is discussed. Experimental demonstrations of the proposed frequency color coded speech spectrograms generated by the proposed white-light optical processing technique are given.
