Vocal types of children with high risk of cerebral palsy before 17 months of age
腦性麻痺高風險兒童17個月大之前發音型態分析
摘要
The purpose of this study is to investigate early phonetic patterns and characteristics in 4 infants with high risk of cerebral palsy (CP) with protophone (Oller, 2000) codings. Recordings at either home or hospital from each infant before 17 months of age were selected for analysis. Six vocal types (Buder, Warlaumont, & Oller, 2013), vowel, growl, squeal, cry, laugh and others, were utilized to categorize those utterances based on subjective judgement of a trained coder. Major findings are: 1) The ratio of squeal to growl was generally higher in most recording samples; 2) Squeal with the feature of raucous was found frequently in two infants; 3) The distribution of vocal types in infants with risk of cerebral palsy around one year of age presents the similar tendency: others > vowel > squeal > growl. Although individual differences affect the results, the preliminary discovering tries to show the induction of vocalization feature in infants with high risk of CP under six types of protophones. More data and analysis are required to establish the profile of early phonetic patterns of children with CP.

本研究中分析四位腦性麻痺高風險嬰兒的發音型態與其特徵。每位嬰兒皆採用17個月前於家中或者醫院內進行錄音之音檔。以Oller（2000）六種「原型音」類別（近似大人母音、沙啞喉音、假音尖聲、哭聲、笑聲以及其他）（Buder, Warlaumont, & Oller, 2013）將嬰兒所發出的聲音由受過訓練之轉寫者進行語音分類。分析結果顯示：（1）在四位嬰兒中，假音尖聲的比例大多高於沙啞侯音；（2）帶有粗糙特性的假音尖聲在兩位嬰兒中出現較為頻繁；（3）在接近一歲時，嬰兒語言發音型態分佈約呈現：其他＞近似大人母音＞假音尖聲＞沙啞喉音。這個初步研究歸納整理腦性麻痺嬰兒發音特性，研究結果呈現相當大的個體差異。後續蒐集更多語料以及分析整理可勾勒出腦性麻痺嬰兒更清楚發音特徵的輪廓。
