Investigating the Determinants of IoT Device Continuance Intentions: An Empirical Study of Smart Speakers Through the Lens of Expectation-Confirmation Theory

IoT device market has grown rapidly in recent years, with many researches have been done to investigate the devices’ adoption factors. However, it is crucial understand how maintain users’ continuance intention. This study, based on post-acceptance model of Expectation Confirmation Model (ECM), investigates impact early-stage personal traits (personal innovativeness), social influence (normative and informational), familiarity, diffusion devices (in particular, smart speakers) measured by continuation intention speakers. We tested research hypotheses using data from 364 speaker users, analyzed partial least square technique Smart-PLS. The analysis results revealed that satisfaction a very strong positive Perceived usefulness, confirmation, innovativeness are positively associated via satisfaction. Social influence, represented normative informational showed significant intention, high degree familiarity weakens intention; however, no relationship between
