Four female native speakers of Modern Greek listened to 465 synthetic vowel tokens with Fl frequencies ranging from 250 to 800 Hz and F2 frequencies ranging from 900 to 2900 Hz in 50 Hz steps. They were asked to identify each stimulus as one of the five vowels of Modern Greek or to reject it if they thought it could not be a vowel of their language. The subjects rejected about 64 percent of the tokens as not possible vowels. The remaining points were plotted in an F I by F2 space with the codes assigned by each subject and in a composite space, where only the points identified with the same response by at least three subjects were used. The results replicated those of Hawks and Fourakis [1], except that the code for the vowel [e] was assigned to many more points than the codes for the other wowels.
