Description of intervention(s) / exposure
Participants are requested to repeat sounds which are recorded on a mobile device (Tablet). Voice sounds include the voicing of the letters "oooooo" "mmmmm", "aaaaaa" "pppppp". The duration of the experiment is less than 5 minutes. The participant's recorded voice sounds are immediately saved electronically along with their #ID and sent directly to RMIT for secure storage and analysis.
Data collection sessions for participants diagnosed with Parkinson's disease will be conducted face-to-face from the participating Neurology clinic in Dandenong as well as Goulburn Valley Health (GVH), Shepparton, Victoria.
All experiments are conducted by the researchers from the School of Engineering, RMIT University or by a Movement disorders Nurse at GVH.

Summary
Brief summary
Speech impairment is an early sign of Parkinson’s disease. Analysis of features of voice may be used as a diagnostic tool for the detection of Parkinson’s disease and in the assessment of its severity. In addition, people living in rural and remote communities often have difficulties in accessing specialist physicians for both diagnosis and continued assessment of Parkinson’s disease. The ultimate aim of this work is to develop an automated diagnostic tool for the assessment of speech impairments associated with Parkinson’s disease that may be used remotely. Patients will be able to record their voice on their personal device. Voice recordings will be analysed and the recorded voice and analysis sent to the specialist physician.
The aim of this study is to ascertain features of the voice that are most useful in identifying differences in voice features between Parkinson’s disease patients and healthy age-matched controls using a mobile device. The hypothesis is that Parkinson’s disease patients will exhibit significantly different voice features compared with healthy age-matched controls.
