The work aims to explore a voice interaction design strategy tailored for the elderly sports scene within communities, so as to provide the better voice interaction experience for the sports health of the elderly. Based on questionnaire surveys and user interviews, the functional requirements of the elderly groups for subdivision service functions and intelligent voice design elements in sports scenes were analyzed and sorted out, and the intelligent voice interaction design strategy for the elderly sports scene was put forward combined with expert evaluations. On this basis, an intelligent voice interaction prototype was designed to carry out the experiments of demonstration evaluation and "The Wizard of Oz" in multiple communities to obtain the evaluation of voice interaction and system service usability by elderly users. The feasibility and effectiveness of the design strategy were verified. The intelligent voice interaction design tailored for the elderly sports scene should highlight the importance of monitoring physical health indicators and providing exercise guidance and recording and feedback on exercise data in elderly sports voice interaction design. Additionally, it should emphasize the need for intelligent voice design elements like pace, volume, interactive initiative, tonal quality, and wake-up phrases. Just as importantly, different intelligent voice design elements varied under specific service functions to match user preferences. The research results offer valuable insights and guidance for the voice interaction design in elderly sports scenes within communities, which is a novel and pertinent direction under the trend of aging society.
