Exploring Strategies For Modeling Sign Language Phonology, Lee Kezar, Riley Carlin, Tejas Srinivasan, Zed Sehyr, Naomi Caselli, Jesse Thomason

Communication Sciences and Disorders Faculty Articles and Research

Like speech, signs are composed of discrete, recombinable features called phonemes. Prior work shows that models which can recognize phonemes are better at sign recognition, motivating deeper exploration into strategies for modeling sign language phonemes. In this work, we learn graph convolution networks to recognize the sixteen phoneme “types” found in ASL-LEX 2.0. Specifically, we explore how learning strategies like multi-task and curriculum learning can leverage mutually useful information between phoneme types to facilitate better modeling of sign language phonemes. Results on the Sem-Lex Benchmark show that curriculum learning yields an average accuracy of 87% across all phoneme types, outperforming …

Objective Discrimination Of Bimodal Speech Using Frequency Following Responses, Can Xu, Fan-Yin Cheng, Sarah Medina, Erica Eng, René Gifford, Spencer Smith

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Bimodal hearing, in which a contralateral hearing aid is combined with a cochlear implant (CI), provides greater speech recognition benefits than using a CI alone. Factors predicting individual bimodal patient success are not fully understood. Previous studies have shown that bimodal benefits may be driven by a patient's ability to extract fundamental frequency (f0) and/or temporal fine structure cues (e.g., F1). Both of these features may be represented in frequency following responses (FFR) to bimodal speech. Thus, the goals of this study were to: 1) parametrically examine neural encoding of f0 and F1 in simulated bimodal speech conditions; 2) examine …

Trumpet Directivity From A Rotating Semicircular Array, Samuel D. Bellows, Joseph E. Avila, Timothy W. Leishman

Directivity

The directivity function of a played musical instrument describes the angular dependence of its acoustic radiation and diffraction about the instrument, musician, and musician’s chair. Directivity influences sound in rehearsal, performance, and recording environments and signals in audio systems. Because high-resolution, spherically comprehensive measurements of played musical instruments have been unavailable in the past, the authors have undertaken research to produce and share such data for studies of musical instruments, simulations of acoustical environments, optimizations of microphone placements, and other applications. The authors acquired the data from repeated chromatic scales produced by a trumpet played at mezzo-forte in an anechoic …

Schwalje, Jihwan Woo, Young Min Na, Ann Holmes, Jean M. Hong, Camille C. Dunn, Marlan R. Hansen, Bruce J. Gantz, Bob Mcmurray, Timothy D. Griffiths, Inyong Choi

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Objectives: Understanding speech-in-noise (SiN) is a complex task that recruits multiple cortical subsystems. Individuals vary in their ability to understand SiN. This cannot be explained by simple peripheral hearing profiles, but recent work by our group (Kim et al. 2021, Neuroimage) highlighted central neural factors underlying the variance in SiN ability in normal hearing (NH) subjects. The present study examined neural predictors of SiN ability in a large cohort of cochlear-implant (CI) users. Design: We recorded electroencephalography in 114 postlingually deafened CI users while they completed the California consonant test: a word-in-noise task. In many subjects, data were also collected …

Recursive Functional Learning In Nonfluent Aphasia, Gerald C. Imaezue

Dissertations, Theses, and Capstone Projects

People with nonfluent aphasia (PWNA) require feedback from an external agent as well self-feedback to facilitate performance of language production tasks. The extent to which PWNA can use self-feedback alone to improve their task performance is unknown. In addition, it is argued that self-feedback may reinforce or minimize performance errors over time. To test whether either is the case, we introduce an original learning mechanism, recursive functional learning, which uses self-feedback loops to optimize recursively multiple subsystems (cognitive and linguistic subsystems) that PWNA engage during task performance. We used this mechanism to underpin a novel automated procedure we developed, recursive …

Communication Sciences and Disorders Faculty Articles and Research

Reading comprehension is an essential skill. It is unclear whether and to what degree typography and font personalization may impact reading comprehension in younger readers. With advancements in technology, it is now feasible to personalize digital reading formats in general technology tools, but this feature is not yet available for many educational tools. The current study aimed to investigate the effect of character width and inter-letter spacing on reading speed and comprehension. We enrolled 94 children (kindergarten–8th grade) and compared performance with six font variations on a word-level semantic decision task (Experiment 1) and a passage-level comprehension task (Experiment 2). …

Multicultural Assessment Practices: A Phenomenological Study Examining Speech-Language Pathologists' Self-Efficacy, Paola Jessica Flores

Doctoral Dissertations and Projects

The purpose of this phenomenological study was to understand speech-language pathologists’ (SLP) self-efficacy beliefs toward assessing culturally and linguistically diverse (CLD) students within public elementary schools in California. Bandura’s self-efficacy theory guided this study since it evaluated SLPs’ belief in their capacity to manage their motivation, behavior, and social environment to carry out appropriate assessment procedures for CLD students. As not all students from CLD backgrounds are accurately identified, gathering the SLPs’ lived experiences regarding current assessment practices helped provide insight into the appropriate identification of SLI. Participants included SLPs employed by rural public school districts in California, with students …

The Directional Effect Of Target Position On Spatial Selective Auditory Attention, Heesung Park

Dissertations, 2020-current

Spatial selective auditory attention plays a crucial role in listening in a mixture of competing speech sounds. Previous neuroimaging studies have reported alpha band neural activity modulated by auditory attention, along with the alpha lateralization corresponding to attentional focus. A greater cortical representation of the attended speech envelope compared to the ignored speech envelope was also found, a phenomenon known as 'neural speech tracking’. However, little is known about the neural activities when attentional focus is directed on speech sounds from behind the listener, even though understanding speech from behind is a common and essential aspect of daily life. The …

Neural Mechanisms Related To The Enhanced Auditory Selective Attention Following Neurofeedback Training: Focusing On Cortical Oscillations, Hwan Shim, Leah Gibbs, Karsyn Rush, Jusung Ham, Subong Kim, Sungyoung Kim, Inyong Choi

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Selective attention can be a useful tactic for speech-in-noise (SiN) interpretation as it strengthens cortical responses to attended sensory inputs while suppressing others. This cortical process is referred to as attentional modulation. Our earlier study showed that a neurofeedback training paradigm was effective for improving the attentional modulation of cortical auditory evoked responses. However, it was unclear how such neurofeedback training improved attentional modulation. This paper attempts to unveil what neural mechanisms underlie strengthened auditory selective attention during the neurofeedback training paradigm. Our EEG time–frequency analysis found that, when spatial auditory attention was focused, a fronto-parietal brain network was activated. …

Electronic Theses and Dissertations

The unique set of impairments and limitations presented by students with autism spectrum disorder (ASD) make the accessing of campus-based nonacademic resources more difficult and complicated than their typically developed peers. Each year, the rate of students entering college with disabilities continues to grow, but their mental well-being is relatively poor. The purpose of this qualitative case study was to apply the conceptual framework of the Andersen behavioral model of health services use (ABMHSU) to the experiences of college students with ASD to understand and predict their utilization of campus-provided mental health resources. The participants were seven college students with …

The Effect Of Visual Feedback On Vocal Compensation Abilities In Individuals With Post-Stroke Aphasia, Marissa Rylee Olson

Theses and Dissertations

Speech production is a complex and highly organized process comprised of various sensory and perceptual components. Post-stroke aphasia can impair speech production abilities by interrupting individuals’ ability to detect and correct speech errors and produce their targeted behavior. Contemporary models of speech production aim to understand the relationship between sensory systems and the human ability to produce perceptually accurate speech. This study seeks to understand the relationship between visual feedback and vocal compensation abilities in individuals with post-stroke aphasia to determine the effectiveness of incorporating visual feedback into therapeutic expressive language intervention. It was hypothesized that that the multi-sensory experimental …

Pattern-Based Target Selection For Treatment Of Irregular Past Tense: A Single-Case Experimental Design For Children With Dld, Kirsten M. Hannig Russell, Amy Wilder, Julie L. Wambaugh

Faculty Publications

Purpose: Many children with developmental language disorder (DLD) demonstrate difficulty inflecting irregular past tense verbs. We evaluated using phonological-based patterns (i.e., schemas) to select targets for treatment of irregular verb inflection for children with DLD. We hypothesized this approach would result in acquisition of treated verbs, generalization to untreated verbs within the same phonological schema, and increased use of correct irregular verbs in naturalistic contexts.

Method: Treatment was provided to three 7-year-old participants with DLD in the context of multiple baseline design across behaviors and participants. Phonological schemas included vowel change, final alveolar, and dual change irregular verbs. Treatment was …

Non-Negative Matrix Factorization Improves The Efficiency Of Recording Frequency-Following Responses In Normal-Hearing Adults And Neonates., Fuh-Cherng Jeng, Tzu-Hao Lin, Breanna N Hart, Karen Montgomery-Reagan, Kalyn Mcdonald

Ambulatory and Primary Care Articles

OBJECTIVE: One challenge in extracting the scalp-recorded frequency-following response (FFR) is related to its inherently small amplitude, which means that the response cannot be identified with confidence when only a relatively small number of recording sweeps are included in the averaging procedure.

DESIGN: This study examined how the non-negative matrix factorisation (NMF) algorithm with a source separation constraint could be applied to improve the efficiency of FFR recordings. Conventional FFRs elicited by an English vowel/i/with a rising frequency contour were collected.

RESULTS: The improvements of FFR recordings, defined as the correlation coefficient and root-mean-square differences across a sweep series of …

Biobehavioral Synchrony In Autism Spectrum Disorder, Carly Glenn Moser

Theses and Dissertations

Social communication difficulties are a core feature of autism and are associated with a range of long-term consequences, including persistent deficits in pragmatic language and fewer and poorer quality friendships. High-quality synchronous interactions between parents and their children play a crucial role in children’s social functioning. The theory of biobehavioral synchrony suggests that the dyadic coordination of behavioral and physiological processes is essential to maximally benefit from a communicative exchange. Respiratory sinus arrhythmia (RSA) serves as an indicator of physiological regulation and is reduced in those with autism; thus, dyadic coordination of RSA may also be impacted and could play …
