Twelve vowels were paired with each other in all combinations and each vowel was represented in both the initial and final positions of the pairs. Four speakers recorded randomized lists with whispered and voiced speech-types. Eight-nine listeners responded to the signals by indicating which member of each pair sounded higher in pitch. The data were treated by a method of paired comparisons Guilford, Case V, and a rank order correlation was made showing relative relationships between speech-types. The results indicate, at least for those vowels that showed significant differences, that tonality may not be the sole determinant of listeners pitch judgments. A comparison of the rank orders of the present study and a rank order from a previous physical investigation provided further support to the hypothesis that the relative pitch of vowels is not independent of the vowel itself.
