A Matter of Time: A Web-Based Investigation of Rest and Sleep Effects on Speech Motor Learning

CONCLUSIONS: A single session of speech motor training promotes observable change to speech production behavior. Specifically, practice facilitates acoustic similarity to the target. Moreover, although a 12-hr postpractice period of rest appears to promote productions that are less variable, only the productions of those who slept are perceived as more accurate by listeners. This may point to sleep's role in contextualizing the acoustic goal of the production to the learner's own vocal tract and its role as a protective mechanism during learning. These results are unaccounted for under existing models and offer potential for future educational and clinical applications to maximize speech motor learning.SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.24707442.PMID:38056482 | DOI:10.1044/2023_JSLHR-22-00309
