Speech Adaptation To Electropalatography In Children's Productions Of /S/ And /ʃ/, Marissa Celaya
Speech Adaptation To Electropalatography In Children's Productions Of /S/ And /ʃ/, Marissa Celaya
Theses and Dissertations
Previous research has investigated adults' ability to adapt their speech when a electropalatographic (EPG) pseudopalate is placed in the oral cavity; however, less is known about how younger speakers who are continuing to develop their motor speech abilities might adapt their speech to the presence of the device. This study examined the effect of an EPG pseudopalate on elementary school-aged children's ability to produce the fricatives /s/ and /ƒ/. Audio recordings of six children were collected at eight time intervals including before placement of the pseudopalate, at 30-minute increments for two hours with the pseudopalate in place, immediately following removal …
Acoustic Analysis Of Prolonged Vowels In Adolescents And Young Adults With Friedreich's Ataxia, Kaylea Hardin
Acoustic Analysis Of Prolonged Vowels In Adolescents And Young Adults With Friedreich's Ataxia, Kaylea Hardin
Electronic Theses and Dissertations
This study employed spectral analyses for acoustic measures of sustained vowel productions from a group of 20 adolescents and young adults with Friedreich's Ataxia (FA) and compared findings with a group of 20 age-equivalent and gender-matched normal control participants. State-of-the art spectral analyses from the Analysis of Dysphonia in Speech and Voice (ADSV) program, developed for various voice disorders from Kay Elemetrics, were applied to initial 2 second sustained vowel segments of the vowels /a/, /i/, and /o/. Spectral analyses included averages and standard deviations of Cepstral Peak Prominence (CPP), Cepstral Peak Prominence Standard Deviation (CPP SD), Low/High Spectral Ratio …
