Abstract
The goal was to recognize sustained vowel-like sounds and their
allophones in one syllable words. A bank of filters and a digital
sampler provided a data base for a polynomial curve fitting routine.
The frequency range under investigation was 500-1000 Hz. A COMCOR CI
5000 analog computer and an XDS 9300 digital computer were used.
Although coefficient correlation was ineffective, several recommendations
for system improvement are made.
