INcorporating VoIce AcTivated Communication Aids Into Everyday Communication

Dysarthria is a speech disorder resulting in speech that is slow, slurred and difficult to understand, limiting a person's opportunities to study, work, and develop relationships.

People with dysarthria often use communication aids to help them to communicate creating spoken messages using a keyboard, touchscreen or joystick. Communication aids can increase independence but are often too slow to keep pace with normal conversation.

Developments in speech recognition technology have led to apps which can learn to recognise a set of words or sounds spoken by the individual with dysarthria, and connect these with a clear spoken output. The investigator's previous research provides some evidence that these voice input communication apps may be faster than traditional communication aids. This study aims to find out who can benefit from this technology, and what support they will need to use it successfully. This information can be used by professionals involved in providing communication aids, and will help the investigators to plan further research into their effectiveness.

This research has two phases:

1. 20-30 individuals with dysarthria will be asked to use a voice input communication app for 6 months. The investigator's will collect information on whether VocaTempo improves their communication, and helps participants to reach their goals. 2. Focus groups will be held with professionals involved in providing and supporting people with communication aids, to understand factors affecting their ability to provide the support identified as needed in part 1 of the research.

The investigators have a panel of communication aid users, who are advising and contributing throughout the study, for example, helping the investigators to identify informal support networks to recruit participants from. The investigators will let people know about the findings through support groups used by people with dysarthria, publications read by people involved in providing communication aids, and academic papers and conferences.
