语音助手的用户经常报告说，他们陷入了使用设备进行有限交互的模式，比如查看天气和设置闹钟。然而，目前还不清楚有限的使用是否部分是由于缺乏对设备功能的了解。我们招募了10个不同的家庭参与为期一个月的Echo Dot部署研究，使我们能够调查：1）家庭了解并参与哪些功能，以及2）家庭如何探索，发现和学习使用Echo Dot。通过家庭与设备互动的录音以及部署前后的访谈，我们发现家庭的使用范围随着时间的推移而稳步下降，家庭通过反复试验，询问Echo Dot本身以及通过朋友和家人等外部影响者了解功能。正式的外部学习影响因素，如制造商的电子邮件，影响力较小。从创新理论的传播，我们描述了如何基于家庭的语音界面可能被定位为一个近端的用户，并通过描述自己的功能，使用即时学习，基于家庭的语音界面成为一个值得信赖的学习影响者，用户可以从中发现新的功能。
Users of voice assistants often report that they fall into patterns of using their device for a limited set of interactions, like checking the weather and setting alarms. However, it's not clear if limited use is, in part, due to lack of learning about the device's functionality. We recruited 10 diverse families to participate in a one-month deployment study of the Echo Dot, enabling us to investigate: 1) which features families are aware of and engage with, and 2) how families explore, discover, and learn to use the Echo Dot. Through audio recordings of families' interactions with the device and pre- and post-deployment interviews, we find that families' breadth of use decreases steadily over time and that families learn about functionality through trial and error, asking the Echo Dot about itself, and through outside influencers such as friends and family. Formal outside learning influencers, such as manufacturer emails, are less influential. Drawing from diffusion of innovation theory, we describe how a home-based voice interface might be positioned as a near-peer to the user, and that by describing its own functionality using just-in-time learning, the home-based voice interface becomes a trustworthy learning influencer from which users can discover new functionalities.
