Study Information

Our research proposes a new technique for people affected by dysarthria- type of speech impairment- to interact with virtual home assistants such as Google Home and Amazon Alexa. The proposed technique overcomes dysarthric users’ communication difficulties and enables them to use these devices with non-verbal sound cues. We would like to answer how using nonverbal voice cues will improve the interaction with the virtual home assistants.


Currently we are conducting a pilot study to test the system developed. We are seeking participants to take part in this study with the following criteria:

  • Aged 18+ and diagnosed with dysarthria (mild-moderate).
  • Do not have any other medical condition that affects language production (e.g aphasia).
  • Have the capacity to give consent.

The study will involve two tasks: Sending voice commands to the system and filling out questionnaires about your experience. The approximate time for finishing the experiment is around one hour

Location: Online or Abacws building at Cardiff University. (We can discuss other options if required)
