An extensive pattern of atypical neural speech-sound discrimination in newborns at risk of dyslexia.
2019
Objective: Identifying early signs of developmental dyslexia, associated with deficient speech-sound processing, is paramount to establish early interventions. We aimed to find early speech-sound processing deficiencies in dyslexia, expecting diminished and atypically lateralized event-related potentials (ERP) and mismatch responses (MMR) in newborns at dyslexia risk. Methods: ERPs were recorded to a pseudoword and its variants (vowel-duration, vowel-identity, and syllable-frequency changes) from 88 newborns at high or no familial risk. The response significance was tested, and group, laterality, and frontality effects were assessed with repeated-measures ANOVA. Results: An early positive a…
Brain responses to speech sounds in infants and children with and without familial risk for dyslexia
2015
Dyslexia, a specific reading disability, runs in families. Therefore, the risk for a child to become dyslexic increases multifold if reading difficulties occur in the family. One risk factor for dyslexia is a deficit in speech perception. Using EEG, speech sound discrimination was found to be more demanding than non- speech discrimination in typical readers in Study I. In Study II, in children with dyslexia in 3rd grade, enhanced brain responses were observed and found to be associated with better performance in reading accuracy, spelling accuracy and phonemic length discrimination tasks. The brain responses of the most accurate readers in the dyslexia group originated from a more posterior…
Kestääkö ääni? : laulunopetuksen vaikutus opettajaksi valmistuvien äänen laatuun ja ilmaisuun
2017
The aim of this study was to investigate how regular singing lessons and deliberate practice impact future teachers’ voice quality and their expression in speech and singing. Previous research about teachers’ speaking voice has shown that kindergarten teachers and classroom teachers are at high risk of showing symptoms or developing disorders, which weaken their effectiveness of expression. The study is qualitative and experimental and it includes longitudinal vocal education, which lasted one academic year. This thesis was approached theoretically through existential phenomenology with a holistic conception of man. Data was gathered from eleven subjects and divided into three research grou…
Creaky voice and utterance fluency measures in predicting perceived fluency and oral proficiency of spontaneous L2 Finnish
2022
While utterance fluency measures are often studied in rela tion to perceived L2 fluency and proficiency, the effect of creaky voice remains ignored. However, creaky voice is frequent in a number of languages, including Finnish, where it serves as a cue for phrase-boundaries and turn-taking. In this study we inves tigate the roles of creaky voice and utterance fluency measures in predicting fluency and proficiency ratings of spontaneous L2 Finnish (F2) speech. In so doing, 16 expert raters participated in assessing narrative spontaneous speech samples from 160 learn ers of Finnish. The effect of creaky voice and utterance fluency measures on proficiency and fluency ratings was studied using …
