Use of a Voice Assistant to Improve Mental Health in Older People

Participants in the experimental group will test in their homes a device called DIAL, a voice-controlled virtual assistant designed to communicate with the elderly and help them in different contexts. They will use it for four weeks. They will receive an individual training session on how to use the device, an instruction sheet for its use and, in addition, they will receive telephone technical support throughout the study. Finally, the device will be uninstalled and all participants will be called back to answer the same survey they answered before the intervention.
