Kinematic And Acoustic Vowel Changes In Adult Bite Block Speech, Tanner Keith Low Jun 2019

Kinematic And Acoustic Vowel Changes In Adult Bite Block Speech, Tanner Keith Low

Theses and Dissertations

The current study examined the lingual kinematic and acoustic effects of bite blocks on vowels in a sentence context. Twenty adult native English speakers (10 male, 10 female) with no speech, language, or hearing deficits participated in the study. The corner vowels found in the sentence, The blue spot is on the black key again (i.e., /u/, /É‘/, /æ/, /i/), were measured kinematically and acoustically immediately before and after bite block insertion. The participants' speech was audio-recorded and their lingual articulatory movements were measured with a Northern Digital Instruments Wave electromagnetic articulograph. The sensor coils were attached to three different …


The Effects Of Distracting Background Audio On Spontaneous Speech, Kacy Nicole Chapman May 2019

The Effects Of Distracting Background Audio On Spontaneous Speech, Kacy Nicole Chapman

Theses and Dissertations

This study examined the changes that occur in spontaneous speech when speakers are distracted by background audio. Forty young adults answered open ended questions under five audio conditions (pink noise, movie dialogue, heated debate, classical music, and contemporary music) and a silent condition. Acoustic parameters assessed during the sessions included mean and variability of the fundamental frequency (F0), mean and variability of intensity, speaking time ratio, and disfluency ratio. It was hypothesized that there would be significant increases in the mean and variability of F0 as well as the mean and variability of intensity. There were statistically significant increases in …
