Voice-Based Interaction for an Aging Population: A Systematic Review

In the past twenty years, voice-based systems have emerged as a technology with high usability and accessibility. Research in the field of Human-Computer Interaction (HCI) has investigated this trend and how these systems can bridge the gap in technology use across all generations, specifically for older adults. This study aims to conduct a systematic literature review of research on voice-based systems for older adults published in the past twenty years. These articles were obtained from reputed databases, filtered out based on specific eligibility criteria, and perused by the authors of this study. This study answers questions concerning the research methodologies often employed for this particular topic and the trends in existing voice-based systems studied in research experiments. It discusses the benefits of voice technologies for the elderly, their challenges, and how to address them.
