Interspeech Posture In Spanish-English Bilingual Adults, Merrily Rose Shary
Interspeech Posture In Spanish-English Bilingual Adults, Merrily Rose Shary
USF Tampa Graduate Theses and Dissertations
Interspeech posture (ISP) is a term used to define the position of a person’s articulators when they are preparing to speak. Research suggests that ISP may be representative of a speaker’s phonological knowledge in a particular language, as determined empirically with ultrasound measures of the tongue in English-French bilinguals (Wilson & Gick, 2014). It is possible, therefore, that measuring ISP could be a diagnostic tool for determining phonological knowledge in bilingual speakers. However, more information on ISP in typical adult bilingual speakers is needed before diagnostic claims can be made. For example, ISP is believed to be language specific, and …
Velar–Vowel Coarticulation In A Virtual Target Model Of Stop Production, Stefan A. Frisch, Sylvie M. Wodzinski
Velar–Vowel Coarticulation In A Virtual Target Model Of Stop Production, Stefan A. Frisch, Sylvie M. Wodzinski
Communication Sciences and Disorders Faculty Publications
Velar–vowel coarticulation in English, resulting in so-called velar fronting in front vowel contexts, was studied using ultrasound imaging of the tongue during /k/ onsets of monosyllabic words with no coda or a labial coda. Ten native English speakers were recorded and analyzed. A variety of coarticulation patterns that often appear to contain small differences in typical closure location for similar vowels was found. An account of the coarticulation pattern is provided using a virtual target model of stop consonant production where there are two /k/ allophones in English, one for front vowels and one for non-front vowels. Small differences in …
Anticipatory Coarticulation And Stability Of Speech In Typically Fluent Speakers And People Who Stutter, Stefan A. Frisch, Nathan Maxfield, Alissa Belmont
Anticipatory Coarticulation And Stability Of Speech In Typically Fluent Speakers And People Who Stutter, Stefan A. Frisch, Nathan Maxfield, Alissa Belmont
Communication Sciences and Disorders Faculty Publications
This project replicates and extends previous work on coarticulation in velar-vowel sequences in English. Coarticulatory data for 46 young adult speakers, 23 who stutter and 23 who do not stutter show coarticulatory patterns in young adults who stutter that are no different from typical young adults. Additionally, the stability of velar-vowel production is analysed in token-to-token variability found in multiple repetitions of the same velar-vowel sequence. Across participants, identical patterns of coarticulation were found between people who do and do not stutter, but decreased stability was found in velar closure production in a significant subset of people who stutter. Other …
Anticipatory Coarticulation And Stability Of Speech In Typically Fluent Speakers And People Who Stutter Across The Lifespan: An Ultrasound Study, Alissa Joy Belmont
Anticipatory Coarticulation And Stability Of Speech In Typically Fluent Speakers And People Who Stutter Across The Lifespan: An Ultrasound Study, Alissa Joy Belmont
USF Tampa Graduate Theses and Dissertations
This study uses ultrasound to image onset velar stop consonant articulation in words. By examining tongue body placement, the extent of velar closure variation across vowel contexts provides for the measurement of anticipatory coarticulation while productions within the same vowel context provide measurement of extent of token-to-token variation. Articulate Assistant Advanced 2.0 software was used to semi-automatically generate midsagittal tongue contours at the initial point of maximum velar closure and was used to fit each contour to a curved spline. Patterns of lingual coarticulation and measures of speech motor stability, based on curve-to-curve distance (Zharkova, Hewlett, & Hardcastle, 2011), are …
