Assessment of speech nasality in children with Robin Sequence.

PURPOSE: To report the outcomes of primary palatoplasty in Robin Sequence (RS); to verify the relationship between modalities of assessment of nasality; to compare nasality between techniques at palatoplasty. METHODS: This study involved the identification of hypernasality in four modalities: live assessment with 4-point scale; live assessment with cul-de-sac test; multiple listeners' ratings of recorded phrase; nasometric assessment. Live ratings of speech nasality and nasalance scores were retrieved from charts, while a recorded phrase was rated by listeners for occurrence of hypernasality. Agreement between the modalities was established as well as association between nasality, nasal turbulence and age at surgery and at assessment. Fisher's exact test was used to compare findings between surgical techniques. RESULTS: Agreement between nasalance, live assessment with 4-point scale, live assessment with cul-de-sac, and multiple listeners' ratings of recorded samples ranged between reasonable (0.32) and perfect (1.00). Percentage occurrence of hypernasality varied largely between assessment modalities. Mean occurrence of hypernasality was lower for the group submitted to Furlow technique (26%) than the group that received von Langenbeck technique (53%). Only findings obtained live were statistically significant (scale: p=0.012; cul-de-sac: p<0.001). Listeners identified nasal turbulence for 22 (32%) samples out of the 69 recordings, and an association was found between hypernasality and nasal turbulence. CONCLUSION: Lower occurrence of hypernasality was identified for patients with RS in Furlow group. Identification of hypernasality varied largely among the four assessment modalities.

OBJETIVO: Reportar os resultados da palatoplastia primária na Sequência de Robin (SR); verificar a relação entre modalidades de avaliação da nasalidade; comparar nasalidade entre técnicas na palatoplastia. MÉTODOS: Este estudo envolveu a identificação da hipernasalidade em quatro modalidades: avaliação ao vivo com escala de quatro pontos; avaliação ao vivo com teste cul-de-sac; julgamento de gravações por juízes e avaliação nasométrica. Julgamentos ao vivo da nasalidade e escores de nasalância foram obtidos em prontuários, enquanto uma frase gravada foi julgada por juízes para ocorrência de nasalidade. Concordância entre as quatro modalidades foi estabelecida assim como associação entre nasalidade, turbulência nasal e idades na cirurgia e na avaliação. Teste exato de Fisher foi usado para comparar achados entre as técnicas cirúrgicas. RESULTADOS: A concordância entre nasalância, avaliação ao vivo com escala de quatro pontos e com teste cul-de-sac e julgamentos de gravações por juízes variou entre razoável (0,32) e perfeita (1,00). Porcentagem de ocorrência de hipernasalidade variou muito entre as diferentes modalidades. Ocorrência média de hipernsalidade no grupo operado com técnica de Furlow foi menor (26%) do que no grupo que recebeu a técnica de von Langenbeck (53%). Somente os resultados avaliados ao vivo foram estatisticamente significantes (escala: p=0,012; cul-de-sac: p<0,001). Juízes ouviram turbulência nasal em 22 (32%) das 69 gravações e uma associação entre hipernasalidade e turbulência nasal foi encontrada. CONCLUSÃO: Ocorrência de hipernasalidade foi menor para os pacientes com SR que receberam a técnica de Furlow. Identificação da hipernasalidade variou grandemente entre as quatro modalidades de avaliação. .

The interaction of lexical and phrasal prosody in whispered speech.

The production and perception of Dutch whispered boundary tones, i.e., phrasal prosody, was investigated as a function of characteristics of the tone-bearing word, i.e., lexical prosody. More specifically, the disyllabic tone-bearing word also carried a pitch accent, either on the same syllable as the boundary tone (clash condition), or on the directly adjacent syllable (no clash condition). In a statement/question classification task listeners showed moderate, but above-chance performance for both conditions in whisper, which, however, was much worse as well as slower than in normal speech. The syllabic rhymes of speakers' productions were investigated for acoustic correlates of boundary tones. Results showed mainly secondary cues to intonation, that is, cues that are present in whisper as in normal speech, but minimal compensatory cues, which would reflect speakers' efforts to enhance their whispered speech signal in some way. This suggests that multiple prosodic events in close proximity are challenging to perceive and produce in whispered speech. A moderate increase in classification performance was found when that acoustic cue was enhanced that whispering speakers seemed to employ in a compensatory way: changing the spectral tilt of the utterance-final syllable improved perception of especially the poorer speakers and of intonation on stressed syllables.

Subtyping stuttering II: contributions from language and temperament.

UNLABELLED: This paper is the second in a series of two articles exploring subtypes of stuttering, and it addresses the question of whether and how language ability and temperament variables may be relevant to the study of subtypes within the larger population of children who stutter. Despite observations of varied profiles among young children who stutter, efforts to identify and characterize subtypes of stuttering have had limited influence on theoretical or clinical understanding of the disorder. This manuscript briefly highlights research on language and temperament in young children who stutter, and considers whether the results can provide guidance for efforts to more effectively investigate and elucidate subtypes in childhood stuttering. Issues from the literature that appear relevant to research on stuttering subtypes include: (a) the question of whether stuttering is best characterized as categorical or continuous; (b) interpretation of individual differences in skills and profiles; and (c) the fact that, during the preschool years, the interaction among domains such as language and temperament are changing very rapidly, resulting in large differences in developmental profiles within relatively brief chronological age periods. EDUCATIONAL OBJECTIVES: The reader will be able to: (1) discuss possible associations of language ability and temperament to the development of stuttering in young children; (2) summarize the subtyping research from the literature on language ability and temperament in young children; (3) generate directions for future research of stuttering subtypes drawn from the literature related to language ability and temperament in young children.
