Abstract

聴取実験により,口蓋裂児の発話に対する了解度・異常度を調査した.対象音声は,声門破裂音を主症状とする口蓋裂児3名,健常児3名の発話による単語12個と文6個である.文は,名詞,助詞,動詞からなり,名詞以外には声門破裂音が含まれていない.聴取者は,4歳,5歳,6歳の健常児と,大学生・大学院生である.分析の結果,以下のことが明らかになった.(1)すべての年齢群において,健常児の発話よりも口蓋裂児の発話に対する了解度は低かった.(2)口蓋裂児の発話に対する了解度は,成人に比べて4歳,5歳,6歳児のほうが低かった.(3)成人では単語よりも文の了解度が高かったが,子どもでは違いがみられなかった.(4)成人と6歳児では,健常児の発話よりも口蓋裂児の発話に対する異常度の評価が高かった.一方,4歳児と5歳児では口蓋裂児と健常児の発話に対する異常度の評価に違いはみられなかった.

This study investigates the degree of intelligibility and abnormality in the speech of normal children and the speech of children with cleft palate who have problems with glottal stops. Seventy-eight children four to six years of age and sixty-four college and graduate students listened to twelve words and six sentences spoken by three children with repaired cleft palate and by three normal children. Glottal stops and hypernasality or hoarseness characterized the speech of the children with repaired cleft palate. Sentences were made up of two parts: subject/topic and predicate. For the children with repaired cleft palate, the initial words contained glottal stops but the final words none. The main findings were as follows. (1) All listeners judged the intelligibility of the speech of the children with cleft palate as lower than that of normal children. (2) Children aged four to six could not understand the speech of children with cleft palate as well as adults. (3) Adults could understand more cleft palate speech in sentences than in words. (4) Adults and children six years of age felt cleft palate speech to be more abnormal than did children of four and five years of age.
