Vowel-initial glottalization constitutes a cue to prosodic prominence, realized on a strength continuum from creaky phonation to complete glottal stops. While there is considerable research on children’s early utilization of acoustic cues for stress marking, less is understood about the specific implementation of vowel-initial glottalization in American English. Eight sequences of function + novel words were elicited from groups of 5-to-8-year-olds, 8-to-11-year-olds, and adults. Children exhibit a similar rate of prevocalic glottalization to adults but differ in its phonetic implementation, producing a higher rate of glottal stops compared to creaky phonation with respect to adults.

儿童言语中元音声母声门化中优先使用全声门塞音：来自小说单词的证据


元音声母声门化构成了韵律突出的提示，是在从嘎吱作响的发声到完全声门停止的强度连续体上实现的。虽然对于儿童早期利用声学线索进行重音标记的研究已有相当多的研究，但对美式英语中元音声母声门化的具体实施了解较少。从 5 至 8 岁儿童、8 至 11 岁儿童和成人组中引出了 8 个功能 + 新词序列。儿童的声门前声门化率与成人相似，但其语音实现方式不同，与成人的嘎吱声发声相比，儿童产生更高的声门塞音率。
