Abstract
Objective: The aim of this study is to investigate the voice and appearance personality of representative smart speakers in Korea through emotional vocabularies, and is to identify the factors affecting the personal satisfaction of smart speakers.
Background: Recently, various kinds of smart speakers have been spreading. Such smart speakers have various appearances and voices, and conversational interactions have their own personalities. However, the study on what kind of personality users prefer is still insufficient. In addition, it is difficult to find out whether the congruence between design and voice personality affects user satisfaction.
Method: In this study, the voice and appearance personality of four smart speakers sold in Korea were separately evaluated using seven emotional vocabularies: funnyserious, casual-formal, respectful-irreverent, enthusiastic-matter of fact, warm-cold, talkative-silent, active-inactive. Then, the satisfaction of each speaker was evaluated.
Results: In the evaluation results of the emotional vocabularies on voice and appearance personality, there were significant differences between the four smart speakers. In addition, there were significant differences in the satisfaction of the four types of smart speakers. In particular, some smart speakers have shown a very large gap between voice and appearance personality.
Conclusion: The participants preferred a polite, friendly, and warm voice. On the other hand, too serious, formal and cynical voices could have a negative impact on satisfaction. Meanwhile, the congruence between voice and appearance does not have a big impact on user satisfaction.
Application: The results of this study can be used to design the personality of smart speakers.
