Vowel space area changes in children with dysarthria., 2023
Choi, J., Hwang, K., & Levy, E. S.
Vowel quadrilateral areas based on first (F1) and second (F2) formant measures of the corner vowels /i/, /æ/, /a/ and /u/ were determined from words produced by six children with dysarthria and six age-mates with normal neurological histories and speech production. The children's F1 × F2 vowel areas were used to test hypotheses about (a) effect of dysarthria on vowel area, and (b) relationship between speech intelligibility and vowel area. Results were in agreement with previous investigations of adults with and without dysarthria. Vowel areas for the children with dysarthria were significantly smaller than those of their age-mates without dysarthria, largely due to a reduction in F2 extent that was most obvious for the back vowel /a/. Positive correlations were obtained between vowel areas and scores on a single word (r = .73) and a sentence intelligibility test (r = .64).

Acoustic predictors of ease of understanding in Spanish Speakers with dysarthria associated with Parkinson’s disease., Advance online publication., 2022
Moya-Galé, G., Wisler, A. A., Walsh, S. J., McAuliffe, M. J., & Levy, E. S.
Children with dysarthria secondary to cerebral palsy may experience reduced speech intelligibility and diminished communicative participation. However, minimal research has been conducted examining the outcomes of behavioral speech treatments in this population. This study examined the effect of Speech Intelligibility Treatment (SIT), a dual-focus speech treatment targeting increased articulatory excursion and vocal intensity, on intelligibility of narrative speech, speech acoustics, and communicative participation in children with dysarthria.

Perception of American English consonants /v/and /w/ by Hindi speakers of English, 7, 2021
Grover, V., Shafer, V., Campanelli, L., Whalen, D. H., & Levy, E. S.
This study examined perception of the American English (AE) /v/-/w/ consonant contrast by Hindi speakers of English as a second language (L2). A second aim was to determine whether residence in the US modulated perception of this difficult contrast for proficient bilingual Hindi-English listeners. Two groups of Hindi-English bilinguals (the first resided in the US for more than five years, the second lived in India) and a group of AE-speaking listeners participated in the study. Listeners’ identification and discrimination of nonsense words (e.g., “vagag” vs. “wagag”) were examined. Hindi listeners performed significantly less accurately than AE controls. Accuracy by Hindi listeners was near chance for identification and higher-than-chance for discrimination. Exposure to AE in the US did not improve performance. These results are consistent with previous studies of late L2 learners and extend findings to a population that was proficient in an L2 before arriving in the L2 environment. [Full Text]
