大多数针对老年用户调整语音界面的研究都是自上而下的,通过比较老年用户和年轻用户的交互行为。相反,我们提出了一种自下而上的方法。通过对50名老年人和年轻人之间的447次预约安排对话以及9个模拟口语对话系统进行统计聚类分析,我们发现了两个主要的用户群体,即“社交”群体和“事实”群体。“事实”用户很快适应了系统,并与它们进行了有效的交互。另一方面,“社交”用户更有可能像对待人类一样对待系统,并且不会调整他们的交互风格。虽然几乎所有的“社交”用户都是老年人,但超过三分之一的老年用户属于“事实”群体。认知能力和性别不能预测群体成员。我们的结论是,口语对话系统应该根据观察到的行为来适应用户,而不是年龄。
Most studies on adapting voice interfaces to older users work top-down by comparing the interaction behavior of older and younger users. In contrast, we present a bottom-up approach. A statistical cluster analysis of 447 appointment scheduling dialogs between 50 older and younger users and 9 simulated spoken dialog systems revealed two main user groups, a “social” group and a “factual” group. “Factual” users adapted quickly to the systems and interacted efficiently with them. “Social” users, on the other hand, were more likely to treat the system like a human, and did not adapt their interaction style. While almost all “social” users were older, over a third of all older users belonged in the “factual” group. Cognitive abilities and gender did not predict group membership. We conclude that spoken dialog systems should adapt to users based on observed behavior, not on age.
