Description
In this study, the Bark transform and Lobanov method were used to normalize vowel formants in speech produced by persons with dysarthria. The computer classification accuracy of these normalized data were then compared to the results of human perceptual classification accuracy of the actual vowels. These results were then analyzed to determine if these techniques correlated with the human data.

Description
The purpose of this study was to evaluate the effects of parent training in the Enhanced Milieu Teaching with Phonological Emphasis (EMT+PE) intervention program, using telepractice, on parent strategy use and child speech and language outcomes for children with repaired cleft palate with or without lip (CP/L). Four parent child dyads participated in the study. Child participants ranged in age from 28 to 53 months at the beginning of intervention and all had a diagnosis of nonsyndromic CP/L. Participants received two-to-three parent training sessions and twice weekly telepractice intervention sessions. Parents increased their use of EMT+PE strategies throughout intervention with the Modeling and Expansion and Prompting and Recasting strategies resulting in significant intervention effects. Moreover, parents maintained increased strategy use following the conclusion of direct intervention. A positive improvement in child speech and language outcomes was seen across intervention. This study showed that telepractice is an effective service delivery model for parent training and subsequent intervention session in EMT+PE strategy use to support the speech and language development for children with CP/L.

Description
Purpose: The purpose of this study was to determine the effectiveness of parent training in Enhanced Milieu Teaching with Phonological Emphasis (EMT+PE) using telepractice on the speech and language outcomes of children with cleft lip and/or palate (CL/P).
Method: Three parent-child dyads participated in the study. All child participants had nonsyndromic CL/P and ranged in age from 21 to 27months. Participants received three weekly telepractice intervention sessions, along with a total of three in-person parent training sessions. Intervention and training were conducted by an SLP and trained graduate student.
Results: All speech measures indicated a gain in essential speech skills for all three children when comparing pre-intervention to post-intervention assessment results. Positive improvement was seen across multiple language measures for all participants.
Conclusion: A parent implemented EMT+PE intervention program using telepractice is an effective way to increase child speech and language outcomes for children with CL/P. Speech and language targets should be combined and delivered simultaneously in intervention.

Description
Past studies have shown that auditory feedback plays an important role in maintaining the speech production system. Typically, speakers compensate for auditory feedback alterations when the alterations persist over time (auditory motor adaptation). Our study focused on how to increase the rate of adaptation by using different auditory feedback conditions. For the present study, we recruited a total of 30 participants. We examined auditory motor adaptation after participants completed three conditions: Normal speaking, noise-masked speaking, and silent reading. The normal condition was used as a control condition. In the noise-masked condition, noise was added to the auditory feedback to completely mask speech outputs. In the silent reading condition, participants were instructed to silently read target words in their heads, then read the words out loud. We found that the learning rate in the noise-masked condition was lower than that in the normal condition. In contrast, participants adapted at a faster rate after they experience the silent reading condition. Overall, this study demonstrated that adaptation rate can be modified through pre-exposing participants to different types auditory-motor manipulations.
