The articulatory-to-acoustic relationship for vowels has been studied and discussed a long time, and the well-known "Quantal Theory" developed by Kenneth Stevens in 1972 was used to examine the articulatory-acoustic relation in vowel production. The purpose of this study is to investigate the relationship between the articulation, in terms of the tongue position, and the acoustics, in terms of the formant frequencies, for the vowels in Cantonese. The seven long vowels [i, y, E, re, a, ::>, u] in (C) V syllables in Hong Kong Cantonese were investigated. The Electromagnetic Midsagittal Articulography (EMA) AG 100 was used to record both the articulatory and acoustic data simultaneously from the speakers.

The regression lines of the seven Cantonese vowels indicate that there is a correlation between the variation in the articulation and formant values for the Cantonese vowels. However, the results of the Regression analysis show that the correlation coefficient, i.e. R2 is not statistically significant (p > 0.05) between the formant values, i.e. FI or F2, and the variation in the articulation, i.e. vertical constriction degree or constriction location. The data do not support Stevens' (1972) "Quantal Theory" on the correlation between articulatory position and formant frequency values for vowels. Thus, more work on the "Quantal Theory" should be going on in the future.

Besides the articulatory-acoustic relation for the Cantonese vowels, this study is the first time to present the articulatory data of the tongue position for the Cantonese vowels. These articulatory data are important for determining the quality as well as the appropriate IP A symbols for the vowels in Cantonese.
