Numerous studies have shown the relationship between vocal attractiveness and personality impression. But there were few studies, which examined what voices sound attractive. This study used covariance structure analysis to examine what traits of voice contribute to vocal attractiveness. Ten speakers' voices (5 male, 5 female) were tape-recorded by DAT tape, then they were changed to wav. files (16 bit, 44.1KHz). All speakers were from Kanto area and spoke standard Japanese. 36 undergraduate students participated in the experiment as the listeners. No one had a listening problem. Each listener was asked to be seated in front of a computer and to put the headphones on. The stimuli were presented randomly. After they listened to each voice, they were asked to rate what the voice sounded like using 9 rating scales (clear, comfortable, easy to listen, fast, heavy, high, like, sharp, thick). As a result of Principal Component Analysis, three factors (vocal quality, tone, and intensity) were extracted. High pitch and thickness were components of vocal quality, and clearness and good tempo were of tone. Then a causal model was made in which vocal quality and tone caused the vocal attractiveness. The model was examined by covariance structure analysis with Amos 4. The goodness of fit was very high at [pic](13)=11.8, GFI=. 96, AGFI=. 91, AIC=41.7. Tone of voice (.69) much more contributes to vocal attractiveness than voice quality (.04).
