【 摘 要 】

This thesis explores the articulation of whispered and normally-spoken alveolar consonants through the use of electropalatography (EPG). While whisper is a well-researched topic, most prior studies have been limited to glottal and acoustic examinations. This study aims to directly measure the articulatory changes speech undergoes when it is whispered. Alveolar consonants /t/, /d/, and /n/ were studied in /iCi/, /aCa/, and /uCu/ environments. Maximum center of gravity, average center of gravity, contacted surface area, and contacted surface area variability were measured. Whispered consonants were found to have a greater duration and COG than normal consonants. Whispered consonants also showed evidence of hyperarticulation: they had lower surface area contact percentages and variability versus normal speech.
