Abstract: It has been shown that visual display systems of intonation can be employed beneficially in teaching intonation to persons with deafness and in teaching the intonation of a Foreign language. In this paper, the question is addressed whether important audible differences between two pitch contours correspond with visually conspicuous differences between displayed pitch contours. IF visual feedback of intonation is to be effective in teaching situations, such correspondence must exist. In two experiments, phoneticians rated the dissimilarity of two pitch contours. In the First experiment they rated the two pitch contours auditorily (i.e., by listening to two resynthesized utterances). In the second, they rated the same two pitch contours visually (i.e., by looking at the two contours displayed on a computer screen). The results indicate why visual feedback may be very effective in intonation training if pitch contours are displayed in such a way that only auditorily relevant Features are represented.
