THE ACOUSTIC VOWEL SPACE OF MODERN GREEK AND GERMAN.

This article cites a study that examined the spectral characteristics of vowels in Modern Greek and German. Four speakers of Modern Greek and three speakers of German produced four repetitions of words containing each vowel of their native language. Measurements of the fundamental frequency and the first three formants were made for each vowel token. These measurements were then transformed into log frequency ratios and plotted as points in a three-dimensional auditory-perceptual space. Each vowel token was thus represented by one point, and the points corresponding to each vowel category were enclosed in three-dimensional target zones.
