Evaluation Of Swallowing Related Measures In Different Head And Neck Postures In Healthy Young And Older Adults, Mabell Vargas

FIU Electronic Theses and Dissertations

This study evaluated swallowing related measures (oral transit time and number of swallows, tongue force and lip force) and different head and neck postures in a group of healthy young adults and older adults. Participants consisted of 19 healthy young and 17 healthy old. They were asked to ingest 2 different liquid consistency to measure the time they take to swallow and the number of swallows. The maximum tongue and lip force was measured with the IOPI device for 3 seconds and repeated 3 times.

The results of the study showed that the number of swallows is not significant regardless …

Kemar Hats Head Orientation Directivity, Samuel D. Bellows, Timothy W. Leishman

Directivity

This directivity data set for a KEMAR head head-and-torso simulator (HATS) includes head orientations in 14 directions in 5° steps starting from 0° to 40° and then in 10° steps from 40° to 90°. The full spherical measurements followed at an a = 0.97 m radius with the mouth aperture at the spherical center. The sampling density and distribution followed the AES 5° dual-equiangular sampling standard, omitting the south pole (θ = 180°). Thus, each spherical directivity assessment included 36 polar-angle θ samples and 72 azimuthal-angle ϕ samples. The presented data include 22 1/3-octave bands, ranging from 80 Hz …

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 …

Average Speech Directivity, Samuel D. Bellows, Claire M. Pincock, Jennifer K. Whiting, Timothy W. Leishman

Directivity

Speech directivity describes the angular dependence of acoustic radiation from a talker’s mouth and nostrils and diffraction about his or her body and chair (if seated). It is an essential physical aspect of communication affecting sounds and signals in acoustical environments, audio, and telecommunication systems. Because high-resolution, spherically comprehensive measurements of live, phonetically balanced speech have been unavailable in the past, the authors have undertaken research to produce and share such data for simulations of acoustical environments, optimizations of microphone placements, speech studies, and other applications. The measurements included three male and three female talkers who repeated phonetically balanced passages …

Autoscore: An Open-Source Automated Tool For Scoring Listener Perception Of Speech, Stephanie A. Borrie, Tyson S. Barrett, Sarah E. Yoho Leopold

Psychology Faculty Publications

Speech perception studies typically rely on trained research assistants to score orthographic listener transcripts for words correctly identified. While the accuracy of the human scoring protocol has been validated with strong intra- and inter-rater reliability, the process of hand-scoring the transcripts is time-consuming and resource intensive. Here, an open-source computer-based tool for automated scoring of listener transcripts is built (Autoscore) and validated on three different human-scored data sets. Results show that not only is Autoscore highly accurate, achieving approximately 99% accuracy, but extremely efficient. Thus, Autoscore affords a practical research tool, with clinical application, for scoring listener intelligibility of speech.

Better Than Nothing, But..., Lyman M. Partridge

While the majority of parents, teachers and administrators are fully aware of the importance of a program of hearing conservation in the schools and readily endorse one, I am convinced that they are not aware of the serious inadequacies of the method of testing the hearing ability of school children that is generally used throughout the state of Washington.

Speech Development Aids Elementary Pupils, Amanda Katherine Hebeler

All Faculty Scholarship for the College of Education and Professional Studies

Speech is one of the most obvious indicators of the child's development when he enters school. The five-year-old child should be able to do the following when he enters Kindergarten: a. Express his needs and thoughts in short sentences. b. Use a vocabulary of meaningful words when speaking of common every-day experience. c. Enunciate and pronounce words clearly enough to be understood, not using baby talk. About this same level of achievement should be expected of the six-year-old who has not had Kindergarten.
