Effects Of Speech Cues In French-Speaking Children With Dysarthria, Erika S. Levy, Gemma Moya-Galé, Younghwa Michelle Chang, Luca Campanelli, Andrea A. N. Macleod, Sergio Escorial, Christelle Maillart

Publications and Research

Background: Articulatory excursion and vocal intensity are reduced in many children with dysarthria due to cerebral palsy (CP), contributing to the children’s intelligibility deficits and negatively affecting their social participation. However, the effects of speech-treatment strategies for improving intelligibility in this population are understudied, especially for children who speak languages other than English. In a cueing study on English-speaking children with dysarthria, acoustic variables and intelligibility improved when the children were provided with cues aimed to increase articulatory excursion and vocal intensity. While French is among the top 20 most spoken languages in the world, dysarthria and its management in …

Relationship Between Intelligibility And Response Accuracy Of The Amazon Echo In Individuals With Amyotrophic Lateral Sclerosis Exhibiting Mild-Moderate Dysarthria, Caroline A. Layden

USF Tampa Graduate Theses and Dissertations

There is an ever-growing and increasing amount of technology options that use speech recognition software. Currently, the market includes smartphones, computers, and individual smart home personal assistants that allow for hands-free access to this technology. Research studies have explored the utility of these assistive devices for the completion of activities of daily living; however, there is limited research looking at the accuracy of voice recognition software within smart home personal assistants in populations with disordered speech. In persons with amyotrophic lateral sclerosis (ALS), symptoms include changes to motor functions, speech in particular, and it is unknown how some of these …

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

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 …

Sensorimotor Adaptation Of Speech Using Real-Time Articulatory Resynthesis, Jeffrey J. Berry, Cassandra North, Michael T. Johnson

Speech Pathology and Audiology Faculty Research and Publications

Sensorimotor adaptation is an important focus in the study of motor learning for non-disordered speech, but has yet to be studied substantially for speech rehabilitation. Speech adaptation is typically elicited experimentally using LPC resynthesis to modify the sounds that a speaker hears himself producing. This method requires that the participant be able to produce a robust speech-acoustic signal and is therefore not well-suited for talkers with dysarthria. We have developed a novel technique using electromagnetic articulography (EMA) to drive an articulatory synthesizer. The acoustic output of the articulatory synthesizer can be perturbed experimentally to study auditory feedback effects on sensorimotor …

Speech And Swallowing Rehabilitation In The Home: A Comparison Of Two Service Delivery Models For Stroke Survivors, Katy J. E. Stewart

Theses: Doctorates and Masters

Background and Aims

Speech and swallowing difficulties are common sequelae for people who have suffered a stroke. Recently, there has been an increase in early discharge, community rehabilitation and the use of therapy assistants to support health professionals in stroke rehabilitation. However, the impact of these factors on communication and swallowing outcomes remains under researched. This research explored Rehabilitation in the Home (RITH) Speech Pathology (SP) services for stroke survivors with dysarthria and dysphagia. More specifically, this research investigated whether traditional speech pathology interventions, supplemented with a home practice program are effective, as well as compare usual treatment to that …

The Effect Of Rate Change On The Relative Timing Of Speakers With Multiple Sclerosis, Brandlynn N. Reister

USF Tampa Graduate Theses and Dissertations

Relative timing ratios are a useful measure for determining the temporal regularities of speech. The timing intervals that make up these ratios are thought to be important when creating the motor plan for an utterance (Weismer & Fennell, 1985). In fact, these ratios have been shown to be remarkably stable, even when speakers deliberately increase their rate (Tuller & Kelso, 1984; Weismer & Fennell, 1985). The constancy of these ratios also has been demonstrated in speakers with known speech timing disturbances, like the dysarthrias associated with Parkinson's and Huntington's disease (Goberman & McMillan; Ludlow, Connor, & Bassich, 1987; Weismer & …

Spatiotemporal Coupling Of The Tongue In Amyotrophic Lateral Sclerosis, Mili S. Kuruvilla, Jordan R. Green, Yana Yunusova, Kathy Hanford

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: The primary aim of the investigation was to identify deficits in spatiotemporal coupling between tongue regions in amyotrophic lateral sclerosis (ALS). The relations between disease-related changes in tongue movement patterns and speech intelligibility were also determined.

Methods: The authors recorded word productions from 11 individuals with ALS with mild, moderate, and severe dysarthria using an x-ray microbeam during word productions. A coupling index based on sliding window covariance was used to determine disease-related changes in the coupling between the tongue regions across each word.

Results: The results indicated decreased spatiotemporal coupling of mid-posterior tongue regions and reduced tongue speed …
