Abstract:

The goal of the research 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 was used. Although coefficient correlation was ineffective, several recommendations for system improvement are made. Author
