ABA Fundamentals

A preliminary analysis of computer‐based asynchronous awareness training for public speaking disfluencies

Perrin et al. (2024) · Behavioral Interventions 2024
★ The Verdict

A short computer lesson cuts speech disfluencies without live coaching.

✓ Read this if BCBAs who help adolescents or adults speak more fluently.
✗ Skip if Clinicians working only with early childhood language.

01Research in Context

01

What this study did

Perrin et al. (2024) tested a self-paced computer program. The program teaches speakers to notice their own disfluencies.

Four adults used the module on their own time. No coach sat with them. The team tracked speech errors before and after.

02

What they found

Every participant spoke more smoothly after the training. They also said the program was easy to use.

Gains showed up when they gave live talks, not just on the computer.

03

How this fits with other research

Montes et al. (2021) ran a similar study but used live coaching plus video review. Their combo worked best. The new study drops the coach and still helps, showing the computer part can stand alone.

Marano et al. (2020) reviewed fifty-four studies. They found staff can master new skills through self-guided modules. Perrin’s work extends that idea to public-speaking fluency.

Vollmer et al. (1996) taught spelling on a computer. Learners later wrote the words by hand with no extra drills. Perrin saw the same jump: computer practice moved to real-life speeches.

04

Why it matters

You can assign the module as homework. Clients practice awareness without using your staff hours. Check progress with a quick speech sample later. This frees you to run other programs while fluency still improves.

03Original abstract

AbstractSimple habit reversal training is effective at reducing public speaking disfluencies; however, the time and resources necessary to implement this intervention may reduce practicality for widespread adoption. The purpose of the present study was to evaluate the effectiveness of asynchronous awareness training. Four participants completed a computer‐based training consisting of response description and practice detecting recorded disfluencies prior to taking a quiz in which they scored the frequency of disfluencies in a recorded speech. Relative to baseline, all participants' rates of disfluencies decreased following training. In addition, acceptability ratings were high and all participants indicated greater willingness to participate in asynchronous training than in‐person training.
