Speech Motor Learning for Healthy Adults
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to explore how the brain learns and produces speech by testing various methods to enhance speech-motor learning. Participants will engage in activities such as naming pictures, reading, and listening to sounds while researchers collect data on their speech patterns. The trial seeks healthy adults who speak American English, have normal hearing, and no history of communication, neurological, or psychological disorders.
As an unphased trial, this study offers participants the chance to contribute to groundbreaking research in speech-motor learning.
Will I have to stop taking my current medications?
If you are taking medications that affect sensorimotor functioning, you will need to stop taking them to participate in this trial.
What prior data suggests that these protocols are safe for improving speech-motor learning?
Research has shown that the treatments under study for improving speech skills are generally safe. For example, enhanced auditory-motor awareness has improved speech clarity without major side effects. This treatment involves methods like auditory training, which helps people understand speech better in noisy environments without harm.
Another treatment uses visual feedback to aid speech learning. Studies suggest that visual cues can enhance the connection between hearing and speaking. Tests on healthy adults have shown positive results without serious side effects.
These treatments are in the "Not Applicable" phase, focusing on new techniques rather than new drugs or surgeries, eliminating risks from new medications or operations. Overall, current research indicates these treatments are well-tolerated.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it seeks to uncover the brain processes that drive how we learn to speak and produce speech. Unlike typical treatments that focus on symptoms or outcomes, this investigation dives deep into understanding the underlying mechanisms of speech motor learning. By studying healthy adults, the trial aims to shed light on how the brain's intricate networks contribute to seamless speech production. This knowledge could pave the way for breakthroughs in treating speech disorders, offering new insights that current methods might not address.
What evidence suggests that this trial's protocols could be effective for improving speech-motor learning?
This trial will explore various methods to enhance speech motor learning. Research has shown that awareness of mistakes can significantly aid in improving speech. For instance, making fewer mistakes during practice can lead to more consistent speech later. One arm of the trial will focus on how error awareness contributes to speech motor learning. Another arm will examine the effects of enhanced auditory-motor awareness. Additionally, the trial will study the effects of error-detection training, the impact of speech variability, and the role of augmented visual feedback in improving speech learning. Each approach aims to help participants adjust their speech by connecting sensory feedback with motor actions.16789
