This study of the discrimination of the quality of vowel sounds is made from two points of view; the estimation of the quality of vowels spoken or sung being based on the discrimination of two types of elements, the phonemic and the voice. Consequently when considering the distribution of responses to the stimuli of vowels in any speech communication system one should know two qualities, the phonemical and the vocal.

The mechanism of perceiving quality should be considered from two complementary aspects:

(1) the position of the formants in the absolute scale of frequencies;

(2) the relative positions of the formants. In the case of the latter it is necessary to consider two conditions: on the one hand the ratio of the frequencies of the two principal formants, on the other hand their product.

In detecting the vocal formants the product is more important than the ratio; for the formants of the phonemical element it is the reverse.
