The Brain Processes Underlying Speech Motor Learning and Speech Production

Not Applicable

Recruiting

• Conditions: Healthy Adults
• Interventions: Behavioral: Effects of speech variability on speech motor learning; Behavioral: Effects of enhanced auditory-motor awareness on speech motor learning; Behavioral: Contributions of error awareness to speech motor learning; Behavioral: Effects of error-detection training on speech motor learning; Behavioral: Enhancing auditory-to-motor mapping with augmented visual feedback

• Registration Number: NCT05918679
• Lead Sponsor: Arizona State University

Brief Summary

The aim of this research is to develop protocols that selectively target and improve speech-motor learning processes. Participants will be asked to name pictures, read words/sentences, and listen to sounds while their speech signals will be collected during the study.

Primary Outcome Measures

Name	Time	Method
Change in speech output in response to previously experienced auditory errors	within each session of the study that may last up to 2 hours	In each trial, participants will experience an auditory error while they produce speech (e.g., they may say "head" but hear "had"). Participants' speech will be measured in each trial. The investigators will measure how the participants' speech changes due to auditory errors experienced in previous trials.
Change In Speech Output Immidiately After Hearing Auditory Errors	within each session of the study that may last up to 2 hours	In each trial, participants will experience an auditory error while they produce speech (e.g., they may say "head" but hear "had"). The investigators will measure how the participants' speech changes due to auditory errors that they experience in the current trial.
