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 Boot Camp Approach To Remediating Interdental /S/ In A School-Aged Child, Melanie Ellen Peris
A Boot Camp Approach To Remediating Interdental /S/ In A School-Aged Child, Melanie Ellen Peris
Theses and Dissertations
The relationship between speech articulation therapy dose (frequency, intensity, duration) and treatment outcomes are poorly understood. Identifying optimal therapy doses for specific articulation disorders is essential to providing efficient clinical care. Recent research indicates that intensive speech therapy doses-known as boot camps-may promote rapid improvement and generalization for certain speech disorders. Therefore the present investigation examined the effects of a boot camp speech therapy approach to remediate interdental /s/ production in an 8-year-old male. The boot camp included two days of speech therapy involving visual, tactile, and auditory feedback approaches. Therapy was administered 5.5 hours per day across morning and …

Development Of Psychometrically Equivalent Speech Recognition Threshold Materials For Native Speakers Of Samoan, Jennifer Lane Newman
Development Of Psychometrically Equivalent Speech Recognition Threshold Materials For Native Speakers Of Samoan, Jennifer Lane Newman
Theses and Dissertations
The speech recognition threshold (SRT) is an important measure, as it validates the pure-tone average (PTA), assists in the diagnosis and prognosis of hearing impairments, and aids in the identification of non-organic hearing impairments. Research has shown that in order for SRT testing to yield valid and reliable measures, testing needs to be performed in the patient's native language. There are currently no published materials for SRT testing in the Samoan language. As a result, audiologists are testing patients with English materials or other materials not of the patient's native language. Results produced from this manner of testing are confounded …

Associations Between Linguapalatal Contact Patterns And Spectral Moments For /S/, Leslie Leatham Bennett
Theses and Dissertations
Both acoustic and palatographic measures have proven to be useful in speech science research. However, it is not known how closely or consistently these two measures are associated with each other. Therefore, this study investigated the association between changes in tongue-to-palate contact patterns and simultaneous changes in acoustic spectral moments for the fricative /s/. Twenty adults were fitted with pseudopalates and repeated VCV nonsense syllables consisting of an initial schwa followed by the target consonant /s/ and ending with one of three corner vowels (/i, ɑ, u/). EPG (electropalatography) data were quantified using three custom numerical indices (s-narrow, s-wide, and …

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 …

Inter- And Intra-Subject Variability: A Palatometric Study, Marybeth Corey Sanders
Theses and Dissertations
Electropalatometry (EPM) has proven to be a useful clinical and research tool for measuring tongue-to-palate contact. The goal of this study was to determine whether the development of a database of standardized palatometric articulation files is feasible by examining the variability which exists within and between speakers. Twenty standard American English dialect speakers were fitted with palatometer pseudopalates. Test stimuli were VCV nonsense words using a schwa in the initial position, the 15 palatal consonants, and three corner vowels, /a/, /i/, /u/. From these palatometric recordings a variability index was created to examine intra- and interspeaker variability. Different aspects of …
Neurophysiologic And Behavioral Measures Of Phonetic Perception In Adult Second Language Speakers Of Spanish, Jaden D. Hellewell
Neurophysiologic And Behavioral Measures Of Phonetic Perception In Adult Second Language Speakers Of Spanish, Jaden D. Hellewell
Theses and Dissertations
Infants 6-8 months old are able to identify nearly every speech sound contrast on which they have been tested, regardless of whether that contrast represents an across-category (two different phonemes) phonetic change in their native language or not. A child's ability to identify non-native consonant contrasts greatly diminishes by 11-12 months of age. The present study examined speech sound discrimination in three groups of listeners. Adult second language (L2) listeners of Spanish were compared with native English listeners with no knowledge of Spanish and native Mexican listeners to determine if they would show the ability to discriminate phonetic distinctions that …
