Although many users adopt voice-enabled technology today, there is lack of understanding on voice technology designs suitable for older adults with visual impairments. This study aims at investigating the auditory information processing capability of older adults with visual impairments and their preferences for voice user interfaces and interactions. A convenience sampling method recruited 20 older adults with visual impairments. The auditory information processing capability was measured with a word memory span task, and the Wizard-of-Oz method helped to explore user requirements for voice technology. The word memory span was 3.00 ± 0.34, which leads to the recommendation that information architectures include no greater than three layers of horizontal or vertical menu structures. The majority of the participants (75%) preferred the combination of inbound and outbound calls to interact with the system, and 65% appreciated the interactive, structured navigation menu user interfaces that empower the user to control the system. The study contributes to user-friendly voice technology for older adults with visual impairments.

尽管当今许多用户采用启用语音的技术，但对于适合视力障碍的老年人的语音技术设计仍缺乏了解。这项研究旨在调查视力障碍的老年人的听觉信息处理能力及其对语音用户界面和交互的偏好。一种便利抽样方法招募了20位视力障碍的老年人。听觉信息处理能力是通过单词记忆跨度任务来衡量的，“绿野仙踪”方法有助于探索用户对语音技术的需求。字存储范围为3.00±0.34，这导致建议信息架构包含不超过三层的水平或垂直菜单结构。大多数参与者（75％）更喜欢使用呼入和呼出电话的组合来与系统进行交互，并且有65％的参与者赞赏使用户能够控制系统的交互式，结构化的导航菜单用户界面。该研究有助于为视力障碍的老年人提供用户友好的语音技术。
