Understanding How We Learn to Speak Better

This study is looking for healthy adults to help us understand how the brain learns and produces speech. We are testing different ways to improve speech motor learning, such as changing how much your speech varies, improving your ability to notice errors in your speech, and using visual feedback to help you connect what you hear with how you move your mouth. We also want to see how being more aware of your mouth movements affects speech learning. The main goal is to see how your speech changes when you hear errors. You can join if you are 18 or older, a native American English speaker, have normal hearing, and no history of communication, neurological, or psychological disorders. This study is currently unclear on its recruitment status.

Study design
This interventional study plans to enroll 510 participants. It is not specified if it is randomized, blinded, or what phase it is in.
What's involved
You will be asked to name pictures, read words and sentences, and listen to sounds. Your speech will be recorded during sessions that may last up to 2 hours.
Compensation
Not stated in the trial record.
Follow-up
Your speech output will be measured within each session of the study, which may last up to 2 hours.

What this trial measures

  • Change in speech output in response to previously experienced auditory errorswithin 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 Errorswithin 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.
