COARTICULATION AND EARLY CONSONANT-VOWEL PRODUCTIONS

辅音和元音的相互依赖性在牙牙学语和早期的话是有据可查的。 在同时牙牙学语和单词的协同发音的比较可能揭示儿童的新兴语言技能的信息。 这个项目的三个具体目标是比较并发牙牙学语和单词的协同发音的变化;相关的协同发音的变化，第一个单词;和描述并发牙学语和单词的协同发音。 十个蹒跚学步的孩子，产生15-25个单词，将在与主要照顾者的自由游戏中录音。 语音产品，包含初始/B/，/d/，和/g/，将被分类为串音或词，并进行声学分析。 轨迹方程度量将用于获得估计评分的标准误作为协同发音的变异性指标，并获得斜率以描述协同发音模式。 辅音和元音库存将提交。将进行适当的统计分析，以进行比较和相关性分析。

Consonant and vowel interdependencies in babbling and early words are well documented. A comparison of coarticulation in concurrent babbling and words may reveal information on the child's emergent language skills. The three specific aims of this project are to compare variability of coarticulation in concurrent babbling and words; correlate variability of coarticulation to first words; and describe coarticulation of concurrent babbling and words. Ten toddlers, producing 15-25 words, will be audio-taped during free play with a primary caregiver. Speech productions, containing initial /b/, /d/, and /g/, will be classified as babble or word and analyzed acoustically. The locus equation metric will be used to obtain standard error of estimate scores as a variability index for coarticulation and to obtain slopes to describe coarticulation patterns. Consonant and vowel inventories will be presented. Appropriate statistical analyses will be conducted for comparisons and correlations.
