Exploring Communication Apprehension And Its Relationship To Communication Attitude And Socio-Communicative Functioning In Children With Velopharyngeal Insufficiency, Agnieszka Dzioba 2014 Western University

Exploring Communication Apprehension And Its Relationship To Communication Attitude And Socio-Communicative Functioning In Children With Velopharyngeal Insufficiency, Agnieszka Dzioba

University of Western Ontario - Electronic Thesis and Dissertation Repository

Myriad findings on children with velopharyngeal insufficiency (VPI) indicate the potential for this population of children to experience feelings of apprehension specific to communication and the potential for other psychological and social difficulties. The purpose of the present investigation was to explore the construct of communication apprehension (CA) and its potential relationship to social and communicative functioning in a diverse group of children with VPI. Potential linkages between CA and multiple socio-communicative constructs including attitude, speech satisfaction, speech and language skill, social competence, and speech severity were explored in a cohort of children with and without VPI, followed by an ...

Brittany Bernal - Sensorimotor Adaptation Of Speech Through A Virtually Shortened Vocal Tract, Brittany A. Bernal 2014 Marquette University

Brittany Bernal - Sensorimotor Adaptation Of Speech Through A Virtually Shortened Vocal Tract, Brittany A. Bernal

Ronald E. McNair Scholars Program 2014

The broad objective of this line of research is to understand how auditory feedback manipulations may be used to elicit involuntary changes in speech articulation. We examine speech sensorimotor adaptation to supplement the development of speech rehabilitation applications that benefit from this learning phenomenon. By manipulating the acoustics of one’s auditory feedback, it is possible to elicit involuntary changes in speech articulation. We seek to understand how virtually manipulating participants’ perception of vowel space affects their speech movements by assessing acoustic variables such as formant frequency changes. Participants speak through a digital audio processing device that virtually alters the ...

Across-Speaker Articulatory Normalization For Speaker-Independent Silent Speech Recognition, Jun Wang, Ashok Samal, Jordan Green 2014 University of Nebraska - Lincoln

Across-Speaker Articulatory Normalization For Speaker-Independent Silent Speech Recognition, Jun Wang, Ashok Samal, Jordan Green

CSE Conference and Workshop Papers

Silent speech interfaces (SSIs), which recognize speech from articulatory information (i.e., without using audio information), have the potential to enable persons with laryngectomy or a neurological disease to produce synthesized speech with a natural sounding voice using their tongue and lips. Current approaches to SSIs have largely relied on speaker-dependent recognition models to minimize the negative effects of talker variation on recognition accuracy. Speaker-independent approaches are needed to reduce the large amount of training data required from each user; only limited articulatory samples are often available for persons with moderate to severe speech impairments, due to the logistic difficulty ...


Pedigree Structure And Kinship Measurements Of A Mid-Michigan Community: A New North American Population Isolate Identified, Joseph D. Bonner, Rachel Fisher, James Klein, Qing Lu, Ellen Wilch, Karen H. Friderici, Jill L. Elfenbein, Debra L. Schutte, Brian C. Schutte 2014 Wayne State University

Pedigree Structure And Kinship Measurements Of A Mid-Michigan Community: A New North American Population Isolate Identified, Joseph D. Bonner, Rachel Fisher, James Klein, Qing Lu, Ellen Wilch, Karen H. Friderici, Jill L. Elfenbein, Debra L. Schutte, Brian C. Schutte

Human Biology Open Access Pre-Prints

Previous studies identified a cluster of individuals with an autosomal recessive form of deafness that resides in a small region of mid-Michigan. We hypothesized that affected members from this community descend from a defined founder population. Using public records and personal interviews, we constructed a genealogical database that includes the affected individuals and their extended families as descendants of 461 settlers who emigrated from the Eifel region of Germany between 1836 and 1875. The genealogical database represents a 13-generation pedigree that includes 27,747 descendants of these settlers. Among these descendants, 13,784 are presumed living. Many of the extant ...


Production Of Complex/Compounds Sentences In The Spontaneous Speech Of Typically Developing Children And Children With Williams Syndrome, Maureen Boyle 2014 Minnesota State University, Mankato

Production Of Complex/Compounds Sentences In The Spontaneous Speech Of Typically Developing Children And Children With Williams Syndrome, Maureen Boyle

Journal of Undergraduate Research at Minnesota State University, Mankato

Literature claims individuals with Williams syndrome (WS), a rare congenital genetic mental retardation syndrome, easily engage in conversation and demonstrate unique and advanced linguistic skills compared to typically developing peers (TDP). These claims are supported by limited empirical evidence, however. One method of judging advanced linguistic skills is to compare the production of complex/compound sentences of children with WS and their TDP. The purpose of the study was to determine whether children with WS use more complex/compound sentences than children who are typically developing. Twelve subjects participated in the study. Six subjects with WS (SWS), mean age 15 ...


The Use Of Paralinguistics In Spontaneous Speech Of Children With Williams Syndrome And Typically Development Children, Kelly Ritter, Evan Panitzke, Emily Kruse 2014 Minnesota State University, Mankato

The Use Of Paralinguistics In Spontaneous Speech Of Children With Williams Syndrome And Typically Development Children, Kelly Ritter, Evan Panitzke, Emily Kruse

Journal of Undergraduate Research at Minnesota State University, Mankato

This project investigated selected aspects of paralinguistics in spontaneous speech of speakers with Williams syndrome. Speakers with Williams syndrome “are noted for their well developed vocabulary, relatively complex and syntactically correct sentences, and their ability to spin a good tale. In contrast, their reasoning usually remains at a pre-operational or preschool level, and they typically have difficulty grasping cause-effect relations” (Semel & Rosner, 2003, p. 5). This research focused on an area of communication called paralinguistics which involved the use of nonspeech sounds for communication. Specifically, we looked at the frequency of laughing and sound effects produced during conversation. Ten participants ...


The Effects Of Target Spectrum, Noise, And Reverberation On Auditory Cue Weighting In Sound Localization, Tran M. Nguyen 2014 Western University

The Effects Of Target Spectrum, Noise, And Reverberation On Auditory Cue Weighting In Sound Localization, Tran M. Nguyen

University of Western Ontario - Electronic Thesis and Dissertation Repository

Sound localization in the horizontal plane depends on interaural time difference (ITD) and interaural level difference (ILD) cues, which are both available in wideband sounds. Previous studies have directly measured listener weighting of those cues only under quiet, anechoic conditions, but not in the presence of noise and reverberation, which can degrade both ITD and ILD. This study examined the effects of changes in target spectral profile, background noise, and reverberation on sound localization performance and cue weighting strategies. Listeners reported locations of targets that were presented over headphones in virtual auditory space. ITD and ILD were manipulated by attenuating ...


The Inter-Relationship Between Core Language Skills And Social Competence In Preschool Children, Clarissa Lau 2014 Western University

The Inter-Relationship Between Core Language Skills And Social Competence In Preschool Children, Clarissa Lau

University of Western Ontario - Electronic Thesis and Dissertation Repository

Language skills provide preschoolers with the foundational skills needed to socially interact, but little is known about the relationship between specific language skills and broad constructs of social competence. Sixteen preschoolers between 3-5 years with varying language abilities were recruited. Descriptive and correlational analyses were conducted to examine the relationships between speech, syntax, semantics, coherence, and literacy skills and social cooperation, social independence and social interaction. The main finding of this study showed that literacy skills as measured by the Numbers, Letters and Words subtest (K-SEALS) and word knowledge and retrieval as measured by the Semantics subscale (CCC-2) were significantly ...


Verb Use In Parkinson's Disease, Swati S. Nikumb 2014 Western University

Verb Use In Parkinson's Disease, Swati S. Nikumb

University of Western Ontario - Electronic Thesis and Dissertation Repository

Verb-specific impairments in their use and comprehension are well documented in persons with Parkinson’s disease (PD). The grammatical and the motor theories have been proposed as possible explanations for verb impairments. The purpose of this study is to describe the use of low-motion and high-motion content verbs in PD in everyday conversation and to determine which theory best supports these findings. In this cross-sectional prospective study, conversation samples were collected and analyzed from participants with PD and their spouses in a mealtime context. Results indicated that total verb use on a proportional basis was not significantly different between persons ...


The Effect Of Botulinum Toxin Type A On Speech Intelligibility In Oromandibular Dystonia, Beatriz Ysabel Domingo 2014 Western University

The Effect Of Botulinum Toxin Type A On Speech Intelligibility In Oromandibular Dystonia, Beatriz Ysabel Domingo

University of Western Ontario - Electronic Thesis and Dissertation Repository

Speech intelligibility of 10 individuals with OMD was measured before and after receiving BoNT-A injections. Intelligibility was assessed using the PIT (single-word intelligibility), SIT (sentence intelligibility), and a conversational speech task. Five listeners rated the speech intelligibility of these three intelligibility tasks via orthographic transcription and visual analogue scaling (VAS) techniques. BoNT-A was not associated with significant differences in speech intelligibility. Further analysis revealed a significant difference on the PIT VAS intelligibility ratings based on order of presentation, suggesting that listeners rated the first half of words on the PIT (words 1-29) as more intelligible than the second half of ...


Comparing Speech Movements In Different Types Of Noise, Sarah Jane Scott 2014 Brigham Young University

Comparing Speech Movements In Different Types Of Noise, Sarah Jane Scott

All Theses and Dissertations

This study examined the impact of several noise conditions on speech articulator movements during a sentence repetition task. Sixty participants in three age groups ranging from 20 to 70 repeated a sentence under five noise conditions. Lower lip movements during production of a target sentence were used to compute the spatiotemporal index (STI). It was hypothesized that STI would be lower (indicating greater stability) in the silent baseline condition. There were changes in speech production under several of the noise conditions. The duration for the 1-talker condition was significantly shorter when compared to the silent condition, which could be due ...


The Spanish Language Proficiency Of Sequential Bilingual Children And The Spanish-English Language Proficiency Scale, Jessica Maribel Tavizón 2014 Brigham Young University

The Spanish Language Proficiency Of Sequential Bilingual Children And The Spanish-English Language Proficiency Scale, Jessica Maribel Tavizón

All Theses and Dissertations

The challenge facing children learning language bilingually has led to efforts to improve the assessment and treatment of language learning difficulties. One of these efforts is the development and validation of the Spanish-English Language Proficiency Scale (SELPS). Previous research has been performed to validate the scale for English language proficiency but not for Spanish language proficiency. Twenty-four sequential bilingual children produced spontaneous narrative language samples that were rated using the SELPS and coded for language sample variables using the Systemic Analysis of Language Transcripts software. Several language sample variables, most notably the Subordination Index, the number of omitted bound morphemes ...


Story Generation Ability In Four Children With Language Impairment, Monica Leroy Chamberlain 2014 Brigham Young University

Story Generation Ability In Four Children With Language Impairment, Monica Leroy Chamberlain

All Theses and Dissertations

This thesis project focused on the complexity of story generations produced by four children with language impairment across treatment sessions. Specifically, the participants’ utterances were analyzed to determine if the children produced simple story elements and/or more complex cause/effect story elements. The children’s utterances were also analyzed to identify emotion words in order to consider the children’s awareness of the emotions experienced by characters in the stories. All participants approached the story generation task by describing characters and actions based on pictures from the book. Two participants did not express any causal relationships and two participants ...


A Model Of Grammatical Category Acquisition In The Spanish Language Using Adaptation And Selection, Camille Lorraine Judd 2014 Brigham Young University

A Model Of Grammatical Category Acquisition In The Spanish Language Using Adaptation And Selection, Camille Lorraine Judd

All Theses and Dissertations

Most typically developing children have achieved a knowledge of the grammatical categories of the words in their native language by school age. To model this achievement, researchers have developed a variety of explicit, testable models or algorithms which have had partial but promising success in extracting the grammatical word categories from the transcriptions of caregiver input to children. Additional insight into children’s learning of the grammatical categories of words might be obtained from an application of evolutionary computing algorithms, which simulate principles of evolutionary biology such as variation, adaptive change, self-regulation, and inheritance. Thus far, however, this approach has ...


A Model Of Children's Acquisition Of Grammatical Word Categories Using An Adaptation And Selection Algorithm, Teresa Young 2014 Brigham Young University

A Model Of Children's Acquisition Of Grammatical Word Categories Using An Adaptation And Selection Algorithm, Teresa Young

All Theses and Dissertations

Most children who follow a typical developmental timeline learn the grammatical categories of words in their native language by the time they enter school. Researchers have worked to provide a number of explicit, testable models or algorithms in an attempt to model this language development. These models or algorithms have met with some varying success in terms of determining grammatical word categories from the transcripts of adult input to children. A new model of grammatical category acquisition involving an application of evolutionary computing algorithms may provide further understanding in this area. This model implements aspects of evolutionary biology, such as ...


Preliminary Test Of A Real-Time, Interactive Silent Speech Interface Based On Electromagnetic Articulograph, Jun Wang, Ashok Samal, Jordan R. Green 2014 University of Nebraska - Lincoln

Preliminary Test Of A Real-Time, Interactive Silent Speech Interface Based On Electromagnetic Articulograph, Jun Wang, Ashok Samal, Jordan R. Green

CSE Conference and Workshop Papers

A silent speech interface (SSI) maps articulatory movement data to speech output. Although still in experimental stages, silent speech interfaces hold significant potential for facilitating oral communication in persons after laryngectomy or with other severe voice impairments. Despite the recent efforts on silent speech recognition algorithm development using offline data analysis, online test of SSIs have rarely been conducted. In this paper, we present a preliminary, online test of a real-time, interactive SSI based on electromagnetic motion tracking. The SSI played back synthesized speech sounds in response to the user’s tongue and lip movements. Three English talkers participated in ...


The Efficacy Of Social Communication Intervention On Teacher Report Of Sociability For Children With Language Impairment, Julianne Grover Smith Guerra 2014 Brigham Young University

The Efficacy Of Social Communication Intervention On Teacher Report Of Sociability For Children With Language Impairment, Julianne Grover Smith Guerra

All Theses and Dissertations

Recent research indicates that many children with Language Impairment (LI) have difficulty with social communication skills. This study assessed the impact of a social communication intervention on teacher perceptions of social withdrawal in children who received the treatment. The intervention targeted emotion understanding using the presentation of children’s stories, facial picture cards, and journaling. Teacher perception was measured using the three withdrawal subscales of the Teacher Behavior Rating Scale (TBRS): Solitary-Active withdrawal, Solitary-Passive withdrawal, and Reticence. Following treatment all five participants received lower ratings of withdrawn behavior on some of the subscales. Only one participant received a rating indicting ...


Children's Adaptation To Electropalatography: Evidence From Acoustic Analysis Of /T/ And /K/, Kara Brianne Knapp 2014 Brigham Young University

Children's Adaptation To Electropalatography: Evidence From Acoustic Analysis Of /T/ And /K/, Kara Brianne Knapp

All 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 ...
