About the study

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.

What is being tested

• Effects of speech variability on speech motor learning (behavioral)
• Effects of error-detection training on speech motor learning (behavioral)
• Contributions of error awareness to speech motor learning (behavioral)
• Enhancing auditory-to-motor mapping with augmented visual feedback (behavioral)
• Effects of enhanced auditory-motor awareness on speech motor learning (behavioral)

Sponsor: Arizona State University · Participants: 510 · Started: Jun 1, 2023
