Parallel Reference Speaker Weighting For Kinematic-Independent Acoustic-To-Articulatory Inversion, An Ji, Michael T. Johnson, Jeffrey J. Berry

Speech Pathology and Audiology Faculty Research and Publications

Acoustic-to-articulatory inversion, the estimation of articulatory kinematics from an acoustic waveform, is a challenging but important problem. Accurate estimation of articulatory movements has the potential for significant impact on our understanding of speech production, on our capacity to assess and treat pathologies in a clinical setting, and on speech technologies such as computer aided pronunciation assessment and audio-video synthesis. However, because of the complex and speaker-specific relationship between articulation and acoustics, existing approaches for inversion do not generalize well across speakers. As acquiring speaker-specific kinematic data for training is not feasible in many practical applications, this remains an important and …

Effects Of Talker Variability On Spectral Contrast Effects., Asim Mohiuddin

College of Arts & Sciences Senior Theses

Spectral contrast effects are context-dependent effects that influence the way we perceive certain sounds. Evidence of these effects can be seen in experiments where a precursor sound (e.g. a sentence) is followed by a target vowel sound (like /ɪ/ as in "bit" or /ɛ/ as in "bet"). If the precursor's frequency was emphasized in areas more consistent with the frequency of /ɛ/, listeners tend to perceive the target sound to be the opposite i.e. /ɪ/. A recent study shows using sentence precursors from 200 different talkers diminishes these effects questioning previous claims that talker variability has no influence on spectral …

Although more testing is …

Exploring Speech And Language Skills In Gifted Children: A Parent Perspective, Amanda Brewer

Williams Honors College, Honors Research Projects

The purpose of this research study was to examine the speech and language skills of gifted students, and to further look into gifted students who have previously had speech or language therapy. Information pertaining to gifted children, typical speech and language development, and gifted children who have a delay in speech was evaluated. The information was used to develop a survey instrument that asked parents about their gifted child’s speech and language. The overall results of this study confirmed many previously known characteristics of gifted students. It also showed that expressive language skills were less developed than receptive language skills. …

Nineteen students attended the training day. Training included part-task skill learning and immersive simulated scenarios. Students were asked to complete course evaluation forms and participated in focus groups immediately after the day. Seven students participated in a further focus group after a five-week hospital placement within a month of the training day. Four students participated in a focus …

Mouth Asymmetries During Infant Babbling: A Brain Lateralization Study, Cecilia Breazile

Senior Honors Projects, 2010-2019

Although babbling is both prevalent and important in the process of language development, it could be argued that we still do not understand the basic nature of babbling. To further our understanding of the nature of babbling we attempted to find evidence for brain lateralization typical of adult speech acts during early babbling. This study examined infant mouth asymmetries during babbling sequences in search of evidence that babbling is an inherently linguistic act as indicated by the lateralization of the brain. Previously recorded videos of 12 infants, all 9 months of age, were examined, 29 images were captured, and a …

Speech Function In Persons With Parkinson's Disease: Effects Of Environment, Task And Treatment, Carrie E. Rountrey

Dissertations, 2014-2019

Parkinson’s Disease (PD) is a degenerative neurological disease affecting aspects of movement, including speech. Persons with PD are reported to have better speech functioning in the clinical setting than in the home setting, but this has not been quantified. New methodologies in ambulatory measures of speech are emerging that allow investigation of non-clinical settings.

The following questions are addressed: Is speech different between environments in PD and in healthy controls? Can clinical tasks predict speech behaviors in the home? Is treatment proven effective by measures in the home? What can we glean from methods of measurement of speech function in …

Dysarthria: A Study Of Effects On Communication, Casey Johnsen

Senior Honors Projects

Dysarthria is an impairment characterized by slow, weak, and imprecise muscle movements that affect one’s speech and communication. The specific characteristics of dysarthria vary depending on the site and extent of the lesion. Some general examples include articulatory-resonatory incompetence, imprecise consonants, distorted vowels, hypernasality, low pitch, harshness, strained-strangled voice and prosodic disturbances including slow rate. Dysarthria can be found in both children and adults, and is caused by neurologic disorders such as stroke, Down syndrome, cerebral palsy, Parkinson’s disease, or muscular dystrophy. Dysarthria can negatively impact one’s social participation. The extra effort it takes to speak and the frustration of …

The Relationship Of Somatosensory Perception And Fine-Force Control In The Adult Human Orofacial System, Nicole M. Etter

Theses and Dissertations--Rehabilitation Sciences

The orofacial area stands apart from other body systems in that it possesses a unique performance anatomy whereby oral musculature inserts directly into the underlying cutaneous skin, allowing for the generation of complex three-dimensional deformations of the orofacial system. This anatomical substrate provides for the tight temporal synchrony between self-generated cutaneous somatosensation and oromotor control during functional behaviors in this region and provides the necessary feedback needed to learn and maintain skilled orofacial behaviors.

The Directions into Velocity of Articulators (DIVA) model highlights the importance of the bidirectional relationship between sensation and production in the orofacial region in children learning …

Nonword Repetition Performance Patterns In English - Spanish Bilingual Adults And English And Spanish Monolingual Adults, Nadia Arriazola Flores

Open Access Theses & Dissertations

Nonword repetition (NWR) is known to be a less biased measure for assessing language abilities of culturally and linguistically diverse (CLD) children (Dollaghan & Campbell, 1998). NWR is used to examine phonological short-term memory mechanisms (also called working memory), because the tasks require the capability to discriminate, store, remember and reproduce phonological sequences (Baddeley, 1989; Braddeley 1974). The purpose of this study was to collect normative data on the NWR performance of bilingual and monolingual adults. This may contribute to the interpretation of performance in bilingual children by providing the standard of adult-like performance. This study examined the performance patterns …

Relationship Between A Measure Of Social And Emotional Development And Early Communication Development In Young Children With Cleft Palate, Jenna L. Pugh

Electronic Theses and Dissertations

This study was an examination of responses to a standardized assessment of social-emotional behaviors and correlation with speech and language development in young children with cleft palate and/or lip. Twenty-eight participants aged 14-35 months with nonsyndromic cleft palate and or lip were included in this study. The Infant-Toddler Social and Emotional Assessment (ITSEA) was used to identify emerging social and emotional behaviors. Descriptive analysis of ITSEA results was completed. Pearson correlation coefficient and effect size estimates were calculated between ITSEA domain raw scores and measures of speech and language development. A small proportion of participants (14%) showed ITSEA scores beyond …

Acoustic And Perceptual Measurements Of Prosody Production On The Profiling Elements Of Prosodic Systems In Children By Children With Autism Spectrum Disorders, Joshua John Diehl, Rhea Paul

Communication Disorders Faculty Publications

Prosody production atypicalities are a feature of autism spectrum disorders (ASDs), but behavioral measures of performance have failed to provide detail on the properties of these deficits. We used acoustic measures of prosody to compare children with ASDs to age-matched groups with learning disabilities and typically developing peers. Overall, the group with ASD had longer utterance durations on multiple subtests on a test of prosodic abilities, and both the ASD and learning disabilities groups had higher pitch ranges and pitch variance than the typically developing group on one subtest. Acoustic differences were present even when the prosody was used correctly.These …

Evaluation Of Language Of Intervention On Expressive-Receptive Lexical Skills For Preschool Bilingual Children, Blanca Estela Cisneros

Open Access Theses & Dissertations

The purpose of the study was to evaluate the expressive-receptive lexical skills gained in bilingual preschool children for both their native language (L1) and second language (L2) when provided a bilingual vocabulary intervention and compared to contrasting monolingual and controlled conditions. This group study assessed four treatment conditions: monolingual English intervention, monolingual Spanish intervention, bilingual English-Spanish intervention, and a controlled intervention condition receiving math instruction. English and Spanish expressive and receptive lexical skills were the dependent variables measured at pretest and posttest. After a brief 4 week intervention block, the bilingual group achieved greater gains in Spanish expressive lexical skills …

Examining Articulatory Kinematics Using Diadochokinesis In Concussed And Non-Concussed Individuals, Lindsay Deann Dolan

Open Access Theses & Dissertations

ABSTRACT

Cognitive and communicative deficits associated with traumatic brain injury are an active area of research. However, no research to date has reported on the functionality of motor speech following a concussion. A common tool used to evaluate the motor speech status of potentially impaired individuals is the measurement of the diadochokinetic speech rate. The purpose of this study is to investigate diadochokinetic speech rates in individuals who experience a sports-related concussion. Determining the nature and extent of motor speech involvement post concussion will contribute to the diagnosis, prognosis, and management of recovery. The present investigation will determine; (i) if …

Comparing Spoken Language Treatments For Minimally Verbal Preschoolers With Autism Spectrum Disorders, Rhea Paul, Daniel Campbell, Kimberly Gilbert, Ioanna Tsiouri

Communication Disorders Faculty Publications

Preschoolers with severe autism and minimal speech were assigned either a discrete trial or a naturalistic language treatment, and parents of all participants also received parent responsiveness training. After 12 weeks, both groups showed comparable improvement in number of spoken words produced, on average. Approximately half the children in each group achieved benchmarks for the first stage of functional spoken language development, as defined by Tager-Flusberg et al. (J Speech Lang Hear Res, 52: 643–652, 2009). Analyses of moderators of treatment suggest that joint attention moderates response to both treatments, and children with better receptive language pre-treatment do better with …

Vowel Production In Mandarin Accented English And American English: Kinematic And Acoustic Data From The Marquette University Mandarin Accented English Corpus, An Ji, Jeffrey J. Berry, Michael T. Johnson

Speech Pathology and Audiology Faculty Research and Publications

Few electromagnetic articulography (EMA) datasets are publicly available, and none have focused systematically on non-native accented speech. We introduce a kinematic-acoustic database of speech from 40 (gender and dialect balanced) participants producing upper-Midwestern American English (AE) L1 or Mandarin Accented English (MAE) L2 (Beijing or Shanghai dialect base). The Marquette University EMA-MAE corpus will be released publicly to help advance research in areas such as pronunciation modeling, acoustic-articulatory inversion, L1-L2 comparisons, pronunciation error detection, and accent modification training. EMA data were collected at a 400 Hz sampling rate with synchronous audio using the NDI Wave System. Articulatory sensors were placed …

Tracking Articulator Movements Using Orientation Measurements, An Ji, Michael T. Johnson, Jeffrey J. Berry

Speech Pathology and Audiology Faculty Research and Publications

This paper introduces a new method to track articulator movements, specifically jaw position and angle, using 5 degree of freedom (5 DOF) orientation data. The approach uses a quaternion rotation method to accomplish this jaw tracking during speech using a single senor on the mandibular incisor. Data were collected using the NDI Wave Speech Research System for one pilot subject with various speech tasks. The degree of jaw rotation from the proposed approach is compared with traditional geometric calculation. Results show that the quaternion based method is able to describe jaw angle trajectory and gives more accurate and smooth estimation …

Out Of The Mouths Of Babes: Vocal Production In Infant Siblings Of Children With Asd, Rhea Paul, Yael Fuerst, Gordon Ramsay, Kasia Chawarska, Ami Klin

Communication Disorders Faculty Publications

Background: Younger siblings of children with autism spectrum disorders (ASD) are at higher risk for acquiring these disorders than the general population. Language development is usually delayed in children with ASD. The present study examines the development of pre-speech vocal behavior in infants at risk for ASD due to the presence of an older sibling with the disorder. Methods: Infants at high risk (HR) for ASD and those at low risk, without a diagnosed sibling (LR), were seen at 6, 9, and 12 months as part of a larger prospective study of risk for ASD in infant siblings. Standard clinical …

The Hypothesis Of Apraxia Of Speech In Children With Autism Spectrum Disorder, Lawrence D. Shriberg, Rhea Paul, Lois M. Black, Jan P. Van Santen

Communication Disorders Faculty Publications

In a sample of 46 children aged 4-7 years with Autism Spectrum Disorder (ASD) and intelligible speech, there was no statistical support for the hypothesis of concomitant Childhood Apraxia of Speech (CAS). Perceptual and acoustic measures of participants' speech, prosody, and voice were compared with data from 40 typically-developing children, 13 preschool children with Speech Delay, and 15 participants aged 5-49 years with CAS in neurogenetic disorders. Speech Delay and Speech Errors, respectively, were modestly and substantially more prevalent in participants with ASD than reported population estimates. Double dissociations in speech, prosody, and voice impairments in ASD were interpreted as …

Talk To Me: Issues In Acquiring Spoken Language For Young Children With Autism Spectrum Disorders, Rhea Paul

Communication Disorders Faculty Publications

Speech-language pathologists play a critical role in the treatment of children with autism spectrum disorders (ASD) because communication deficits are a primary component of both the diagnostic criteria and the focus of educational services for children with these conditions. Children with ASD almost always are delayed in speech acquisition (Tager-Flusberg, Paul, & Lord, 2005), as well as in other areas of communication. Lack of speech is often the most obvious symptom and greatest cause for concern of parents of toddlers who are eventually diagnosed with ASD, even though closer observation usually reveals additional problems.

The Intelligibility Of Japanese Speakers Of English To Native Speakers Of English, Manabu Aoki

All Master's Theses

This research was conducted to identify the most important English speech sounds which determine non-native English speakers' intelligibility to native speakers of English. The researcher focused on variation of pronunciation by Japanese English speakers of differing levels of proficiency and examined the correlation between their pronunciation and intelligibility to native speakers. The results provided some keys to intelligible English speech and some implications for developing comprehensible speech in teaching English as a second language or English as a foreign language.
