Interventions

  • Effects of speech variability on speech motor learning — BEHAVIORAL
    This intervention will examine whether reducing normal variability of speech could improve error detection and speech motor learning. We will design training tasks to change subjects' speech variability. We will train subjects to decrease/decrease their speech variability. Upon completing the training tasks, subjects will complete a motor learning task.
  • Effects of error-detection training on speech motor learning — BEHAVIORAL
    This intervention will examine whether improving subjects' ability to detect and estimate auditory perturbation could improve speech motor learning. For this purpose, we will design training tasks to change subjects' estimation of the perturbation magnitude. After completing the training tasks, subjects will complete the motor learning task.
  • Contributions of error awareness to speech motor learning — BEHAVIORAL
    This intervention will examine the contributions of error awareness to speech motor learning. Subjects will produce a target word while receiving perturbed auditory feedback with different magnitudes. Subjects will be trained to indicate the magnitude of the error they perceived with or without visual feedback.
  • Enhancing auditory-to-motor mapping with augmented visual feedback — BEHAVIORAL
    This intervention will determine the contributions of enhanced auditory-to-motor mappings to speech motor learning. We will design training tasks in which we will use visual feedback to provide feedback regarding subjects' accuracy of auditory-to-motor mapping.
  • Effects of enhanced auditory-motor awareness on speech motor learning — BEHAVIORAL
    In this intervention, subjects will be trained to control their articulators more accurately and be more aware of their articulators' position and their auditory consequences. After the training tasks, subjects will complete a motor learning task.

Study Details

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.
