Speech Adaptation to Electropalatography in Children's Productions of /s/ and /ʃ/

摘要: Speech Adaptation to Electropalatography in Children’s Productions of /s/ and /ʃ/ Marissa Celaya Department Communication Disorders Master Science Previous research has investigated adults’ ability adapt their speech when a electropalatographic (EPG) pseudopalate is placed the oral cavity; however, less known about how younger speakers who are continuing develop motor abilities might presence device. This study examined effect an EPG on elementary school-aged children’s produce fricatives /ʃ/. Audio recordings six children were collected at eight time intervals including before placement pseudopalate, 30-minute increments for two hours with place, immediately following removal 30 minutes after removal. An acoustic analysis was completed looking consonant duration, spectral mean, variance, relative intensity. Disturbance patterns from noted most measures, noticeably intensity both /ʃ/, as well mean variance Although there relatively high amount variability among within speakers, signs adaptation apparent only some participants. For full often did not occur until removed. future needed, it hoped that this will provide greater understanding pseudopalate.
