| dc.description.abstract | With the trend of artificial intelligence, voice assistant has been increasingly valued in the field of human-computer interaction. Due to its convenient, intuitive, and natural communication capacities, the use of voice assistant has gradually gained wider usage in recent years. The mode of innovative interactions will bring about changes in communication between humans and machines. In the future, voice assistant will more than likely be used in smart homes, voice commerce, or in-vehicle voice systems. It will gradually be integrated into the daily lives of the general public. This research studies and explores the acceptance factors of voice assistant. Using the integrated model of user satisfaction and technology acceptance (Wixom & Todd, 2005), a number of factors are added to the trade-offs including “quality,” “operation,” “personality,” “privacy,” and “interestingness.” As a result, we conducted a survey on the users of voice assistant. The valid samples were 214, and the PLS-SEM structural equation model was used for testing. Research results show that “quality” has a positive effect on user satisfaction, and “operation,” “personality,” and “interestingness” have a positive effect on the attitude of use. In addition, we found that in “quality,” the quality of information is more influential than the quality of the system. Among the “personality,” the “personality trait” of the voice assistant is an important factor that affects the users’ trust. And the most influential personality traits are practical, helpful, and logical. This study provides a more complete framework for exploring the intent of use of voice assistant and is suitable for interpreting applications related to voice assistant services. It can be used by voice assistant developers as a design basis to improve the user experience and create a good interactive environment. | en_US |
