Assessing Perceptual Effects of Interactive Tasks in ALS

This study is looking at how well people understand the speech of individuals with Amyotrophic Lateral Sclerosis (ALS) and others without ALS. Researchers will have listeners hear recorded speech from both groups, produced in different situations (interactive and non-interactive tasks). The listeners will then choose what they heard from a list of words. The main goal is to see if interactive situations change how clearly speech is understood for both groups. This study is for people aged 18 to 65 who are native English speakers, have good hearing, and no known speech, language, or neurological disorders. The study is currently unclear about its recruitment status.

Study design
This is a single-group study planning to enroll 1300 participants. All participants will complete the same tasks remotely.
What's involved
You will participate in one 20-minute session where you listen to recorded speech and indicate what you heard by clicking on words.
Compensation
Not stated in the trial record.
Follow-up
Not specified.

What this trial measures

  • Intelligibility of recorded speechone 20 minute session

    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.
