The goal of this clinical trial is to learn whether noise-augmented feedback using
automatic speech recognition improves intelligibility and social participation in
individuals with Parkinson's disease.
Data collection will be face-to-face at a convenient time for participants. The screening
and assessment sessions will take place in the Communication, Technology, and Language
Diversity Lab (Room 952a), on the 9th floor of the 528 Building at Teachers College,
Columbia University (525W 120th St, New York, NY 10027).
Treatment sessions will be conducted independently by the participant in the
participant's home. Four out of the 16 treatment sessions will be supervised online (via
Zoom) by a licensed speech and language pathologist.
The study involves 5-7 assessment sessions (including one 6-month follow-up) and 16
treatment sessions ( = 1 month). Each participant is expected to be involved in the study
for 7-8 months.
Participants will first attend a screening session to confirm eligibility, which will
involve a hearing screening, a brief cognitive screening, and a brief depression
screening. If the screening is successful, participants will complete two or four
assessment sessions before initiation of the treatment protocol (the number of assessment
sessions depends on their group allocation: immediate treatment or deferred/delayed
treatment).
Screenings will only be completed once, during their first in person visit on the
Teachers College campus.
In the first assessment session participants will be asked to complete voice recordings
and three questionnaires. Participants will complete the same speech tasks and
questionnaires in the rest of the assessment sessions. The number of assessment sessions
(5 versus 7) depends on whether they are assigned to the immediate treatment group or the
delayed treatment group. Group assignments are random, and participants will always
receive the treatment protocol.
Each assessment session is estimated to take 60-90 minutes to complete.
Participants will complete the treatment sessions on their own using your phone and
computer. Participants will be instructed to find a quiet place at home and practice
their exercises at a time when they feel ok and not too tired. They will log in onto our
web-based app, Understand Me for Life, to start their speech session. App instructions
will be provided during the second assessment session for familiarization purposes.
Each session will contain 20 short sentences (between 3 and 7 words in length).
Participants will be asked to try to complete 5 sessions in 1 hour (a total of 100
sentences), taking as many breaks as they may need. Participants will be instructed to
complete 1-hour of speech exercises 4 days a week for 4 weeks. The total number of days
to participate in the treatment study is 16.
