Dual-Task Effects Of Walking On Rate Of Speech, Dayna Kathleen Jablecki

Electronic Thesis and Dissertation Repository

The dual-task effect of walking on rate of speech was measured in 32 healthy young adults. The influence of word meaning and sex on rate of speech was also investigated. A separate inspection time task was used to determine whether speed of information processing (SIP), predicted the degree of dual-task interference of walking on rate of speech. This study revealed that rate of speech was influenced by dual-task interference effects due to the performance of a simultaneous gait task. Pause times suggested a sex effect, demonstrating that while walking, women spent significantly less time pausing between verbal stimuli than men. …

Developing A Drug Delivery System For Treatment Of Vocal Fold Scarring, Aaron Michael Kosinski

Open Access Dissertations

Vocal fold scarring is an affliction that results in the formation of a disorganized and stiff extracellular matrix (ECM) with abnormal ECM component densities & structures including a significant increase in collagen deposition. It is caused by improper healing post injury and results in profound changes in the biomechanical properties of the vocal folds impairing their ability to generate a normal mucosal wave during phonation.

Finding an effective treatment for vocal fold scarring has been elusive. Currently, treatments seek temporary solutions that correct glottal incompetence and reduce stiffness caused by the scar through the augmentation of the vocal folds using …

Predicting Language Impairment Status: A Risk Factor Model, Johanna Maria Rudolph

Open Access Dissertations

The etiology of specific language impairment (SLI) is multifactorial. Research has shown that genetic, environmental, and developmental factors may influence the course of its development. Because many of these factors are present even before a child is born, it is possible that a child's risk of developing the disorder can be identified long before grammatical deficits are observed. The goal of this study was to develop and validate a screening tool to discriminate between children with SLI and typically developing (TD) children using risk factor information including gender, family history of communication or reading disorders, socioeconomic status, maternal and paternal …

Articulatory Distinctiveness Of Vowels And Consonants: A Data-Driven Approach, Jun Wang, Jordan R. Green, Ashok Samal, Yana Yunusova

School of Computing: Faculty Publications

Purpose: To quantify the articulatory distinctiveness of 8 major English vowels and 11 English consonants based on tongue and lip movement time series data using a data-driven approach.

Method: Tongue and lip movements of 8 vowels and 11 consonants from 10 healthy talkers were collected. First, classification accuracies were obtained using 2 complementary approaches: (a) Procrustes analysis and (b) a support vector machine. Procrustes distance was then used to measure the articulatory distinctiveness among vowels and consonants. Finally, the distance (distinctiveness) matrices of different vowel pairs and consonant pairs were used to derive articulatory vowel and consonant spaces …

Effects Of Truncation On Language Sample Analysis In Aphasia, Gerasimos Fergadiotis, Heather Harris Wright

Speech and Hearing Sciences Faculty Publications and Presentations

The goal of this study is to determine if the length of a language sample elicited from a person with aphasia (PWA) is of consequence when making inferences about the patient's functional language ability. When conducting a language sample analysis, a sample representing a snapshot in time is used to make inferences about an individual's language capacity in general. However, current findings are inconclusive regarding the ideal length of the language sample necessary to draw valid conclusions about patients (e.g. Heilman, Nockerts, & Miller, 2010).

Measuring Global Coherence In Aphasia, V. Galetto, S. Kintz, T. West, Heather Harris Wright, Gerasimos Fergadiotis

Speech and Hearing Sciences Faculty Publications and Presentations

Discourse coherence may be conceptualized as representing the listener's ability to interpret the overall meaning conveyed by the speaker. Discourse schemas serve as the organizing frameworks for placing the essential discourse elements within a language sample (Bloom, Borod, & Santschi-Haywoor, Pick, & Obler, 1996; Peterson & McCabe, 1983). When the essential elements are provided a logical consistency of the discourse schema is maintained and the listener perceives the discourse as coherent (Ditman & Kuperberg, 2010; Trabasso, van den Broek, & Suh, 1989; van den Broek, Virtue, Everson, Tzeng, & Sung, 2002). Global coherence refers to the ability to semantically relate …

Modern Prescription Theory And Application: Realistic Expectations For Speech Recognition With Hearing Aids, Earl E. Johnson

ETSU Faculty Works

A major decision at the time of hearing aid fitting and dispensing is the amount of amplification to provide listeners (both adult and pediatric populations) for the appropriate compensation of sensorineural hearing impairment across a range of frequencies (e.g., 160?10000?Hz) and input levels (e.g., 50?75?dB sound pressure level). This article describes modern prescription theory for hearing aids within the context of a risk versus return trade-off and efficient frontier analyses. The expected return of amplification recommendations (i.e., generic prescriptions such as National Acoustic Laboratories?Non-Linear 2, NAL-NL2, and Desired Sensation Level Multiple Input/Output, DSL m[i/o]) for the Speech Intelligibility Index (SII) …

Word Recognition From Continuous Articulatory Movement Time-Series Data Using Symbolic Representations, Jun Wang, Arvind Balasubramanian, Luis Mojica De La Vega, Jordan R. Green, Ashok Samal, Balakrishnan Prabhakaran

CSE Conference and Workshop Papers

Although still in experimental stage, articulation-based silent speech interfaces may have significant potential for facilitating oral communication in persons with voice and speech problems. An articulation-based silent speech interface converts articulatory movement information to audible words. The complexity of speech production mechanism (e.g., co-articulation) makes the conversion a formidable problem. In this paper, we reported a novel, real-time algorithm for recognizing words from continuous articulatory movements. This approach differed from prior work in that (1) it focused on word-level, rather than phoneme-level; (2) online segmentation and recognition were conducted at the same time; and (3) a symbolic representation (SAX) was …

Investigation Of Auditory Encoding And The Use Of Auditory Feedback During Speech Production, Laura E. Beamish

Electronic Thesis and Dissertation Repository

Responses to altered auditory feedback during speech production are highly variable. The extent to which auditory encoding influences this varied use is not well understood. Thirty-nine normal hearing adults completed a first formant (F1) manipulation paradigm where F1 of the vowel /ε/ was shifted upwards in frequency towards an /æ/–like vowel in real-time. Frequency following responses (FFRs) and envelope following responses (EFRs) were used to measure neuronal activity to the same vowels produced by the participant and a prototypical talker. Cochlear tuning, measured by SFOAEs and a psychophysical method, was also recorded. Results showed that average F1 production changed to …

Assessing For And Understanding The Impact Of Hearing Loss In Children, Sally A. Arnold Ph.D.

NYS Child Welfare/Child Protective Services Training Institute

Hearing loss in children may occur unnoticed if the family isn’t knowledgeable about hearing loss and the child is not routinely seen for medical exams or by a school or a service provider. The child welfare caseworker may be in a position to spot a potential hearing loss and make an appropriate referral.

This PowerPoint describes:

Indicators of hearing loss when assessing children;

Hearing milestones by age;

The types of hearing loss;

Appropriate referrals if a hearing loss is suspected.

This PowerPoint can be useful not just for the caseworker’s knowledge, but may be useful in helping parents understand why …

The Role Of The Vestibular And Proprioceptive Systems In Processing Dynamic Sound Localization Cues, Janet Kim

Electronic Thesis and Dissertation Repository

Head movements are known to be beneficial during sound localization because the auditory system can integrate the dynamic cues generated by head movement while maintaining a spatial representation of the position and orientation of the head-in-space. To measure the extent to which vestibular and proprioceptive cues influence processing of dynamic sound localization cues resulting from head rotation, we measured the ability of normally hearing listeners to localize front/back sources of low-frequency sounds while the two modalities were individually or congruently stimulated. Targets were presented over headphones during head rotations using virtual auditory space methods. Dynamic localization cues corresponded to head-in-space …

A Comparison Of Speech Amplification Devices For Individuals With Parkinson's Disease And Hypophonia, Monika Andreetta

Electronic Thesis and Dissertation Repository

One of the most prevalent speech impairments in idiopathic Parkinson’s disease (PD) is hypophonia, a reduction in intensity, which typically decreases intelligibility. Speech amplification devices are a potential solution; however, despite the availability of a broad range of devices, no previous studies systematically compare their efficacy in PD. This study examined the effects of speech task (Sentence Intelligibility Test versus conversation), background noise (no noise versus 65 dB SPL multi-talker noise), and selected devices (ADDvox, BoomVox, ChatterVox, Oticon, SoniVox, Spokeman, and Voicette) for 11 PD and 10 control participants, using outcome measures of speech intensity, speech-to-noise ratio, intelligibility, sound quality, …

Effect Of Concurrent Walking And Interlocutor Distance On Conversational Speech Intensity And Rate In Parkinson's Disease, Cassandra M. Mccaig

Electronic Thesis and Dissertation Repository

This study examined the effects of concurrent walking tasks and interlocutor distance on conversational speech production in fifteen individuals with idiopathic Parkinson’s disease (PD) and fourteen age-equivalent controls. Recent studies of speech in PD have demonstrated that changes in the behavioural conditions and the environmental context can have a powerful effect on the severity of speech symptoms in PD. This investigation focused on changes in speech intensity and speech rate in response to changes in walking speed and interlocutor distance. Results suggest that the introduction of a concurrent walking task significantly increased the conversational speech intensity of both controls and …

A Preliminary Study Of The Articulatory And Acoustic Features Of Forward And Backward Tone Placement In Singing, Krista Wyllys

Masters Theses

A variety of terms exist for describing tone quality in singing, and voice scientists, voice therapists, teachers of singing, and students of singing use different terms to describe the same sound. One aspect of tone quality is tone placement. Teachers of singing often rely on imagery and imitation to elicit correct tone placement from students of singing. More concrete data about what produces forward and backward tone placement could supplement singing teachers’ current practice of using imagery and imitation to elicit a desirable tone quality. This study examined forward and backward tone placement to determine the articulatory gestures and acoustic …

Individual Articulator's Contribution To Phoneme Production, Jun Wang, Jordan R. Green, Ashok Samal

CSE Conference and Workshop Papers

Speech sounds are the result of coordinated movements of individual articulators. Understanding each articulator’s role in speech is fundamental not only for understanding how speech is produced, but also for optimizing speech assessments and treatments. In this paper, we studied the individual contributions of six articulators, tongue tip, tongue blade, tongue body front, tongue body back, upper lip, and lower lip to phoneme classification. A total of 3,838 vowel and consonant production samples were collected from eleven native English speakers. The results of speech movement classification using a support vector machine indicated that the tongue encoded significantly more information than …
