Abstract: Listeners judged the dissimilarity of pairs of synthesized nasal voices that varied on 3 dimensions. Separate nonmetric multidimensional scaling (MDS) solutions were calculated For each listener and the group. Similar 3-dimensional solutions were derived for the group and each of the listeners, with the group MDS solution accounting for 83% of the total variance in listeners' judgements. Dimension 1 (''Nasality'') accounted for 54% of the variance, Dimension 2 (''Loudness'') for 18% of the variance, and Dimension 3 (''Pitch'') For 11% of the variance. The 3 dimensions were significantly and positively correlated with objective measures of nasalization, intensity, and Fundamental frequency. The results of this experiment are discussed in relation to other MDS studies of voice perception, and there is a discussion of methodological issues for future research.
