Voice-activated, artificial intelligence–based assistants (voice AI assistants) have become an integral part of everyday life because they can be easily activated to complete numerous tasks. However, little is known about what motivates people to use them or how these motivations influence users’ post-consumption evaluations and perceptions. This study develops measures to capture uses and gratifications related to voice AI assistants. It identifies five primary motivations for use—social interaction, personal identity, conformity, life efficiency, and information. Results show that the utilitarian motivations of life efficiency and information influence all post-consumption evaluations and behavioral intentions positively (i.e., users’ attitudes, satisfaction, and intentions to continue using voice AI assistants). However, social motivations are also important. Social interaction and conformity motivations also influence user satisfaction, and the conformity motivation shapes individuals’ intentions to continue using voice AI assistants. The findings further demonstrate that users’ motivations influence perceptions of their voice AI assistants’ roles. In keeping with the “Computers Are Social Actors” (CASA) paradigm, users motivated by social interaction are likely to perceive a voice AI assistant as socially attractive and as a friend, whereas users motivated by life efficiency are likely to perceive it as an assistant. Users motivated by information are more likely to perceive a voice AI assistant as technology, while those motivated by social interaction are less likely to do so. The implications of these findings are discussed, and recommendations for future research are provided.

语音激活的基于人工智能的助手（语音AI助手）已经成为日常生活中不可或缺的一部分，因为它们可以很容易地激活以完成许多任务。但是，人们对人们使用它们的动机或这些动机如何影响用户的消费后评估和感知知之甚少。这项研究制定了一些措施，以捕获与语音AI助手相关的用途和满足感。它确定了使用的五个主要动机-社会互动，个人身份，合规性，生活效率和信息。结果表明，生活效率和信息的功利动机对所有消费后评估和行为意图产生积极影响（即，用户的态度，满意度和继续使用语音AI助手的意图）。然而，社会动机也很重要。社交互动和整合动机也会影响用户满意度，整合动机会影响个人继续使用语音AI助手的意图。研究结果进一步表明，用户的动机会影响他们对语音AI助手角色的看法。与“计算机是社会角色”（CASA）范例保持一致，受社交互动激励的用户很可能将语音AI助手视为社交吸引力和朋友，而受生活效率激励的用户则很可能将其视为助手。 。受信息激励的用户更有可能将语音AI助手视为技术，而受社交互动激励的用户则不太可能这样做。讨论了这些发现的含义，
