Interactive voice response (IVR) systems use computer-based voice recognition and software algorithms to conduct human/computer interactions. In recent years, there has been a proliferation of IVR applications in business and healthcare. The available evidence suggests that older people have negative attitudes towards IVR and experience significant difficulties using these systems.
The goal of this project was to identify areas of difficulties in IVR use by older people and propose strategies for improvement.
During two focus groups, we examined older people's perceptions of IVR systems and the most common difficulties experienced by seniors in interacting with these systems. We also recorded their suggestions for improvement of IVR.
Frequency and chi square analyses were performed on the focus groups data. Some of the difficulties reported by participants in this study were congruent with previous findings, but we also uncovered some additional problems, such as frustration for not being able to reach an operator, being asked to wait too long on hold, being unable to recover from mistakes, and an absence of shortcuts in the systems. In addition, significant number of participants indicated that they prefer a system that adjusts to them automatically as opposed to a system that allows for adjustment.
Generally, our findings suggest that the poor acceptability of IVR systems by older people could be improved by designing IVR algorithms that detect difficulties during an ongoing IVR exchange and direct people to different algorithms adapted for each person.
交互式语音应答 (IVR) 系统使用基于计算机的语音识别和软件算法来进行人机交互。近年来,IVR 在商业和医疗保健领域的应用日益普及。现有证据表明,老年人对 IVR 持负面态度,并且在使用这些系统时会遇到重大困难。
本项目的目标是确定老年人在使用 IVR 时遇到的困难领域,并提出改进策略。
在两次焦点小组讨论中,我们研究了老年人对 IVR 系统的看法以及老年人在与这些系统交互时最常遇到的困难。我们还记录了他们对改进 IVR 的建议。
对焦点小组数据进行了频率和卡方分析。本研究参与者报告的一些困难与先前的发现一致,但我们也发现了一些其他问题,例如无法联系到操作员而感到沮丧、等待时间过长、无法从错误中恢复以及系统中没有快捷方式。此外,相当数量的参与者表示,他们更喜欢一个可以自动适应他们的系统,而不是一个允许他们进行调整的系统。
总的来说,我们的研究结果表明,通过设计在正在进行的 IVR 交互过程中检测到困难并将人们引导到为每个人定制的不同算法的 IVR 算法,可以提高老年人对 IVR 系统的较差接受度。
