This research investigates whether Alexa can support speech practice for people with Parkinson’s disease. After eight weeks of home use, nine of ten participants developed stronger voices. Although not a replacement for professional speech therapy, voice assistants could provide accessible, everyday opportunities to practise louder, clearer speech outside clinical settings.

This project developed AI Care, a voice-based caregiving system for people with early-stage Alzheimer's disease. Unlike conventional voice assistants, it uses caregiver-maintained medical records to provide personalised, safety-aware support. By adapting to users rather than requiring users to adapt to technology, AI Care aims to extend safe, independent living at home.
