2018 ASHA CONVENTION PROGRAM BOOK • 229 TECHNICAL RESEARCH SESSIONS • THURSDAY DAY/TIME/ LOCATION/ ROOM SESSION/ AREA/ CONTENT/ LEVEL/TYPE TITLE/ AUTHOR(S) ABSTRACT TH 3:30PM-4:00PM Westin, Galleria Tech G 4539 SLP SLS Introductory Research Methodological Issues in the Assessment of Voicing Errors in Children Benjamin Munson, U of Minnesota; Kiana Koeppe, U of Minnesota; Lindsey Schwartz, U of Minnesota; Katelyn Smith, U of Minnesota; Jessica Bottomley, U of Minnesota; Jan Edwards, U of Maryland, College Park; Mary Beckman, The Ohio St U A critical component of assessments of children’s speech are listener judgments, usually in the form of phonetic transcriptions. The relationship between these judgments and the acoustic characteristics of children’s speech isn’t straightforward. In this project, we examine whether inter-rater differences in judgments of children’s stop consonant voicing are correlated with differences in raters’ own production of voicing. TH 4:30PM-5:00PM Westin, Galleria Tech G 4540 SLP SLS Introductory Research Relationships Between Perceived Age & Perceived Gender in Children’s Speech Benjamin Munson, U of Minnesota; Katherine Bangert, U of Minnesota; McKayla Beaulieu, U of Minnesota; Emily Larson, BA- U of Minnesota Boys and girls’ speech sounds different before puberty. Gender typicality of children’s speech is usually assessed with listener ratings. These ratings are potentially confounded by the age that listeners assume the children they are rating to be. We present results of studies examining the relationship between perceived age and perceived gender, to determine the nature of this potential confound TH 5:00PM-5:30PM Westin, Galleria Tech G 4541 SLP SLS Intermediate Research Longitudinal Analysis of Speech Rate of Novel Utterances & Their Repetitions in Young Children Anna Tendera, U of Alberta; Matthew Rispoli, U of Illinois at Urbana-Champaign; Spenser Halfyard, U of Alberta; Chelsea Inaba, U of Alberta; Sentil Senthilselvan, U of Alberta; Torrey Loucks, U of Alberta Our longitudinal project will contrast speech rate development of spontaneous utterances versus repetitions in young children. Our sample includes four time points between 24 and 36 months of age. The study outcomes provide better understanding of developmental trajectory of a speech rate growth and reveal novel aspects of speech production of original utterances and their repetitions at early ages. TH 6:30PM-7:00PM Westin, Galleria Tech G 4542 SLP SLS Introductory Research Interaction Between Phonation & Articulation: An Acoustic Study of Mandarin Vowels Liqun Yao, Fujian U of TCM; Zhenni Wang, Shanghai Ruijin Rehab Hosp; Yang Chen, Duquesne U; Manwa Ng, The U of Hong Kong The aim of this study was to investigate the possible interaction between formant frequencies of Mandarin vowels and lexical tones. The first two formants were obtained from six Mandarin vowels produced at four different Mandarin tones by young adult speakers. Results revealed significant differences in formants for /ɔ/ and /e/ across different tones, indicating some interaction between phonation and articulation. TH 7:00PM-7:30PM Westin, Galleria Tech G 4543 SLP SLS Intermediate Research Comparing Acoustic Aspects in the Arabic and English Productions by Bilingual Speakers Richard Morris, Florida St U; Sana Tibi, Florida St U; Hany AlSalmi, Florida St U; Olivia Emerson, Florida St U The purpose of this study was to evaluate the acoustic aspects of sound production in Arabic and English. Twelve Arabic and English speaking young adults completed number and paragraph reading tasks. The speakers exhibited greater articulation rate variability across tasks in their second language, English. They exhibited similar second formant transition rates across languages and tasks. TH 6:30PM-7:00PM Westin, Galleria Tech C 4544 SLP SSDC Intermediate Research Mispronunciation Detection Abilities of Preschoolers With & Without Speech Sound Disorders Francoise Brosseau-Lapre, Purdue U; Jennifer Schumaker, Purdue U; Rose Reyling, Purdue U Children ages 4 and 5 years, both with typical speech and with speech sound disorder, completed a mispronunciation detection task targeting omissions and substitutions of the phonemes /k,s,r/ in five word positions/shapes. Children with SSD had difficulties detecting mispronunciations of words compared to children with TD. Implications for assessment and intervention with children with SSD will be discussed. TH 7:00PM-7:30PM Westin, Galleria Tech C 4545 SLP SSDC Intermediate Research Does Speaker Accent Impact Sentence Comprehension in Children With Speech Sound Disorder? Jennifer Harte, U Coll Cork; Pauline Frizelle, U Coll Cork; Fiona Gibbon, U Coll Cork Results showed that children with specific speech sound disorder do not have difficulties comprehending sentences spoken in an unfamiliar regional or non-native accent during a relatively simple sentence comprehension task comprising familiar vocabulary. Moreover, their ability to process accent variation does not differ to typically developing children who are language matched, suggesting that language level may play a role. TH 10:15AM-10:45AM Westin, Carlton 4546 SLP SWAL Introductory Research Successful Infant Feeding: An Evidence Based Systematic Review Memorie Gosa, The U of Alabama; Ambley Chambers, The U of Alabama; Cassidy Kelley, The U of Alabama; Jennifer Barnes, The U of Alabama Successful feeding is a developmental milestone that must be reached for an infant to qualify for discharge from the neonatal intensive care unit (NICU). This evidence based systematic review evaluated the published evidence to determine the variables used to define successful feeding in the NICU. Results indicate successful feeding is not clearly defined in peer- reviewed literature. TH 10:45AM-11:15AM Westin, Carlton 4547 SLP SWAL Intermediate Research The Relation Between Lingual Biomechanics During Swallowing & Swallowing Function in Persons Diagnosed With ALS Bridget Perry, MGH Inst; Rosemary Martino, U of Toronto; Emily Plowman, U of Florida; Kaila Stipancic, MGH Inst; Stacey Sullivan, Massachusetts General Hosp; James Berry, Massachusetts General Hosp; Jordan Green, MGH Inst Impairments in tongue movement and in swallowing function are expected over the course of the disease process in persons diagnosed with ALS. This kinematic study reports on the relation between biomechanical measures of the tongue during swallowing (i.e. tongue range of motion, tongue speed, duration of tongue movement and tongue coordination) and swallow physiology, safety, and efficiency. TH 11:15AM-11:45AM Westin, Carlton 4548 SLP SWAL Intermediate Research Measuring Hyoid Excursion Across the Lifespan: Anatomical Scaling to Control for Variation Danielle Brates, New York U; Sonja Molfenter, New York U Previous literature has demonstrated that sex-based differences in hyoid excursion disappear when size-of-the-system is controlled in young, healthy individuals . This study used established methodology to determine whether an anatomical scalar could be applied to a sample of healthy seniors to control sex-based hyoid movement variation, and to compare these outcomes to those found in healthy young individuals.
