Interactive speech improved vowel intelligibility in people with ALS-related dysarthria

Original source

Comparing vowel intelligibility across interactive and non-interactive tasks in disordered speech.JASA Express Lett · 1 March 2026 (opens in a new tab)

Compass summarised this from the study's abstract.

Study details

Studied in
Human

Vowels were understood more accurately when people with amyotrophic lateral sclerosis (ALS) used clear speech or matched an interactive speaking partner than during habitual speech. Interactive matching was as intelligible as, or more intelligible than, clear speech for some vowels.

Why this matters

The finding may help researchers understand how communication interactions influence speech intelligibility for people with ALS-related dysarthria. It does not establish a treatment or show that interactive matching improves everyday communication or changes clinical care.

Limitations and context

The study describes its findings as a preliminary step and reports results from two experiments. The source summary does not provide the number or characteristics of participants, listener details, or evidence about real-world communication or treatment outcomes.
