论文摘要
语音助手提供了一种方便且免提的方式来访问家庭中的计算，但是语音作为交互方式的关键问题是如何脚手架准确的语音助手心理模型，这一任务是由于隐私和安全问题而复杂的任务。我们介绍了对语音助手用户的调查（n = 1314），以测量对语音助手的信任，安全性和隐私感知，并以不同方式解释了不同级别的在线功能。然后，我们要求参与者重新解释这些语音助手是如何工作的，这表明尽管隐私解释缓解了隐私问题，但信任解释使信任的问题加剧了。参与者的信任，隐私和安全感也将第一方在线功能与语音助理供应商和其他开发人员与第三方在线功能区分开来，对供应商的信任似乎独立于设备说明。我们的发现表明，使用类比来指导用户，针对信任和隐私问题，制造商所需的主要改进以及对该行业竞争的影响。
Voice assistants offer a convenient and hands-free way of accessing computing in the home, but a key problem with speech as an interaction modality is how to scaffold accurate mental models of voice assistants, a task complicated by privacy and security concerns. We present the results of a survey of voice assistant users (n=1314) measuring trust, security, and privacy perceptions of voice assistants with varying levels of online functionality explained in different ways. We then asked participants to re-explain how these voice assistants worked, showing that while privacy explanations relieved privacy concerns, trust concerns were exacerbated by trust explanations. Participants' trust, privacy, and security perceptions also distinguished between first party online functionality from the voice assistant vendor and third party online functionality from other developers, and trust in vendors appeared to operate independently from device explanations. Our findings point to the use of analogies to guide users, targeting trust and privacy concerns, key improvements required from manufacturers, and implications for competition in the sector.
