Effects of listener adaptive temporal adjustment in dialogue on emotional characteristics of speech were investigated by analyzing the speech of teachers directed to hearing-impaired (HI) or normal-hearing (NH) children. 1) Four factors were extracted which accounted for 81% of the total variance in perceptual rating scores on emotions. 2) Factor 1 represented the emotional differences between the read tokens (RD) and the dialogue speech (NH and HI), which were the contrasts between pleasant versus discomfort. 3) Factor 3 represented the differences between HI and the others (RD and NH), which was the contrast between "Slow, Stiff, Intelligible, Strong" versus "Busy, Tense, Rough, Dull". 4) The measures of the temporal structure of speech significantly accounted for the above-mentioned emotional contrasts. These results suggest that the listener-adaptive temporal adjustment of dialogue speech affects not only the segmental characteristics of speech such as devoicing but also prosody-related characteristics of speech such as the emotional profiles.
