Brief Summary
This study will compare two types of assistive devices for communication (a voice amplifier and a personal communication system) in individuals with a speech disorder related to Parkinson's disease. The performance of these two devices will be examined with measures of speech intelligibility and patient questionnaires and rating scales.

Outcome Measures
Primary Outcomes (3)
Speech Intelligibility Score
The Sentence Intelligibility Test will be used to obtain speech intelligibility scores (%) while participants are speaking and using the two communication devices during quiet and 65 decibels of multi-talker background noise. Speech intelligibility scores will be obtained from communication partners who will provide live repetitions of the participant's spoken sentences and from listener transcriptions of the participant's audio recorded spoken sentences.
up to 5 min
Device Performance Rating Score
Visual analogue scales related to physical comfort, visual presentation, sound quality, amplification power, and overall preference will be used by the participant with Parkinson's disease and the associated communication partner to evaluate the devices following the initial 30 minutes of use (treatment) and following 7 days of use (treatment).
30 minutes and 7 days
Device Satisfaction Rating Score
The Speech Amplification Satisfaction Scale and the Quebec User Evaluation of Satisfaction with Assistive Technology Scale will be used by the participant with Parkinson's disease and the associated communication partner to evaluate the devices following 7 days of use (treatment).
7 days
Study Arms (2)
Voice Amplifier
ACTIVE COMPARATORParticipant will be fit with a voice amplifier (ChatterVox) and it will be used during speech testing and during regular conversations over a one week period.
Personal Communication System
EXPERIMENTALParticipant will be fit with a personal communication system (Easy Listener FM system) and it will be used during speech testing and during regular conversations over a one week period.
Interventions
A voice amplifier will be attached to the participant and used for the treatment of low speech intensity (hypophonia) and reduced speech intelligibility in Parkinson's disease.
A personal communication (FM) system will be attached to the participant and used for the treatment of low speech intensity (hypophonia) and reduced speech intelligibility in Parkinson's disease. Personal Communication System
Eligibility Criteria
You may qualify if:
- Diagnosed with Parkinson's disease by a neurologist at least 6 months prior to testing • Exhibit mild to moderate signs and symptoms of Parkinson's disease and hypophonia (reduced speech intensity) • Stabilized on antiparkinsonian medication
You may not qualify if:
- Exhibit severe signs and symptoms of Parkinson's disease • History of stroke or an additional neurological or motor control disorder • History of speech impairment that is unrelated to Parkinson's disease
