About this trial

In this study, we will evaluate how solo, naive listeners perceive the speech of people with amyotrophic lateral sclerosis (ALS) and age-matched speakers produced across interactive and non-interactive contexts with an unfamiliar, naive interlocutor.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

passing the remote hearing screening

having no known speech, language or neurological disorders per self-report

being a native monolingual speaker of American English

having no experience communicating with people with dysarthria

Disqualifiers

None - if volunteer meets the inclusion criteria, then they will be enrolled

Trial design

Design model

Single group

Treatments tested in this trial

  • Listener judgements of speech produced in different tasks

    Behavioral

    Listeners will hear recorded speech of PALS and age-matched speakers across interactive and non-interactive tasks and indicate what they heard by clicking one of four words displayed on the screen. Standard attention checks and minimum performance thresholds (Theodore, 2021) will be used to ensure that listeners are engaged and are able to provide meaningful perceptual judgments.

Primary outcomes

Intelligibility of recorded speech

Perceptual judgments will be provided by solo, naïve listeners who did not participate in the interactions. Listeners will hear recorded speech of PALS and age-matched speakers recorded across the different tasks and indicate what they heard. The score will be expressed in percent. The possible range is between 0-100%. The higher scores mean a better outcome.
