Leveraging Data and Voice Interfaces for Accessible Mobile Telehealth

Mobile telehealth applications have become a primary modality for remote clinical service delivery; however, systematic inclusion of users with diverse disabilities remains insufficiently addressed. This paper presents the Accessible Telehealth Design Framework (ATDF) a four-layer architecture integrating disability-aware interaction modalities, a voice-augmented consultation interface, and a novel Accessibility Quality Index (AQI) for quantitative evaluation. Three disability cohorts (motor impairment, low vision, cognitive disability) were evaluated across three application configurations. ATDF-compliant interfaces achieved AQI improvements of 98.1%, 93.0%, and 76.5% over unmodified baselines. Voice interface integration reduced median task duration by 38% for motor-impaired users. The framework provides a deployable reference architecture for telehealth engineers, clinical informaticists, and regulatory bodies advancing equitable digital health.
