With the development of AI technology, the voice assistant based on human language is spreading. This study is to analyze the factors affecting intention to use of voice assistant with hedonic-system acceptance model (HAM). It includes elements of fun and enjoyment in the acceptance of new technology. The research model which is based on HAM is established to identify factors that are perceived ease of use, emotional interaction, perceived usefulness and perceived enjoyment for intention to use. Basic data are collected from 500 valid samples of voice assistant users and structural equation modeling analysis is performed using AMOS 24 program. Perceived ease of use has a significant effect on both perceived usefulness and perceived enjoyment, therefore it finally affects behavioral intention to use. Emotional interaction affects perceived enjoyment and ultimately affects behavioral intention to use as well.
