Kinematic And Acoustic Adaptation To A Bite Block During Syllable Production, Allison Marie Barney
Kinematic And Acoustic Adaptation To A Bite Block During Syllable Production, Allison Marie Barney
Theses and Dissertations
The purpose of the current study was to gain a better understanding of speech adaptation by examining kinematic and acoustic adaptation to bite block perturbation over time. Fifteen native American English speakers (7 female, 8 male) with no history of speech, language, or hearing deficits participated in the study. Custom bite blocks were created for speakers which created a 10mm interincisal gap when inserted. Speakers produced five repetitions of the sentence, I say ahraw /ərɑ/ (as part of a larger set) prior to bite block insertion, immediately following bite block insertion, 2-mintues post insertion, 4-minutes post insertion, 6-minutes post insertion, …
Articulatory Kinematic Differences During Adaptation To A Bite Block, Madison Ann Mchaley
Articulatory Kinematic Differences During Adaptation To A Bite Block, Madison Ann Mchaley
Theses and Dissertations
The current study examined the effects of bite blocks on articulatory kinematics when producing /r/ within a phrase. Participants consisted of 20 young adults (10 males, 10 females) with no speech, language or hearing disorders. Participants produced the carrier phrase, I say __ with the nonsense words /əri/ (high front vowel), /əræ/ (low front vowel), /əru/ (high back vowel), /ərɑ/ (low back vowel). A Northern Digital Instruments Wave electromagnetic articulograph measured the articulatory movements while the speaker produced the stimuli in two conditions (Pre bite block and post bite block). Bilateral bite blocks were made using Express dental putty, which …
Perceptual Analysis Of Children's Adaptation To An Electropalatography Sensor, Kasey Marie Duffield
Perceptual Analysis Of Children's Adaptation To An Electropalatography Sensor, Kasey Marie Duffield
Theses and Dissertations
The purpose of this study is to observe childrens adaptation to an electropalatographic (EPG) sensor. Sound recordings of six children between the ages of 7;0 and 9;11 sampled at 30-minute intervals over a two-hour period of wearing an EPG sensor were perceptually evaluated to quantify the children's adaptation over time. Twenty native speakers of American English evaluated the pronunciation of a series of words with embedded stops and fricatives produced with and without an EPG sensor in place. When collapsed over speaker and stimulus type, listener ratings decreased significantly after inserting the EPG sensor. Ratings then increased significantly after the …

Children's Adaptation To Electropalatography: Evidence From Acoustic Analysis Of /T/ And /K/, Kara Brianne Knapp
Children's Adaptation To Electropalatography: Evidence From Acoustic Analysis Of /T/ And /K/, Kara Brianne Knapp
Theses and Dissertations
Electropalatography (EPG) is a computer-based device that uses a fitted pseudopalate (similar to an orthodontic retainer) with embedded electrodes to track tongue-to-palate contact during speech for the purposes of providing treatment for a variety of communication disorders. This study evaluated six elementary school-aged children's ability to adapt their speech to the presence of the pseudopalate in their mouth. The participants' adaptation for the consonants /t/ and /k/ was examined over eight time intervals throughout a two and half hour time period. Adaptation was evaluated by measuring the duration, spectral mean, spectral variance, and relative intensity of the target sounds. The …
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 …
A Perceptual Evaluation Of The Effect Of A Pseudopalate On Voiceless Obstruent Production And Motor Adaptation, Megan Ann Cannon Williams
A Perceptual Evaluation Of The Effect Of A Pseudopalate On Voiceless Obstruent Production And Motor Adaptation, Megan Ann Cannon Williams
Theses and Dissertations
Electropalatography (EPG) has proven to be a useful clinical and research tool for measuring tongue-to-palate contact. Research has shown sensorimotor adaptation to an EPG device may be possible following a short period of speech practice. This study was developed in order to better understand how a listeners' perception of speech clarity is effected by the presence of a relatively thin artificial pseudopalate in the speakers' oral cavity. Twenty listeners rated 220 speech stimuli on a visual analog scale ranging from normal to very distorted speech clarity. The stimuli included two different American English sentences. Speech clarity ratings were looked at …
The Effect Of A Pseudopalate On Voiceless Obstruent Production: A Spectral Evaluation Of Adaptation, Karie Lindsay Dean
The Effect Of A Pseudopalate On Voiceless Obstruent Production: A Spectral Evaluation Of Adaptation, Karie Lindsay Dean
Theses and Dissertations
Many studies in speech communication have provided valuable findings concerning the kinematic nature of speech articulation. This type of research often involves introducing an oral device to the vocal tract such as lingual pellets, magnets, and different forms of pseudopalates to track the movement and placement of the articulators. This study examined the effect of an electropalatography (EPG) pseudopalate on the production of five voiceless obstruents (/p, t, k, s/ and /sh/). Acoustic recordings from 20 adult speakers with typical speech production were made during three different speaking conditions: prior to pseudopalate placement, immediately after placement, and following 20 minutes …
