COARTICULATION AND EARLY CONSONANT VOWEL PRODUCTIONS

辅音和元音在喋喋不休和早期单词中的相互依存关系被很好地记录下来。比较同时发音和单词时的协同发音可能会揭示孩子的紧急语言技能的信息。这个项目的三个具体目标是比较同时发音和单词的协同发音的变异性；将协同发音的变异性与第一个单词联系起来；以及描述同时发音和单词的协同发音。10个学步的孩子，15-25个单词，将在与主要照顾者自由玩耍的过程中被录音。语音产物，包括声母/b/、/d/和/g/，将被归类为胡言乱语或单词，并进行声学分析。轨迹方程度量将被用来获得估计分数的标准误差作为协同发音的变异性指标，并获得用于描述协同发音模式的斜率。辅音和元音清单将提供。将进行适当的统计分析，以进行比较和相互关联。

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.
