本文利用纵向声学和发音数据研究了儿童的言语发育。每年从一年级到四年级收集四名女性和四名男性儿童的数据。我们分析了四个角元音的声学和发音特性：//，/i/，/u/和/ A /，每个角元音出现在两个不同的单词（不同的周围环境）。声学特征包括共振峰频率和声门下共振（SGR）。发音特征包括舌曲度（TCD）和舌曲位置（TCP）。基于这些分析，我们观察到基于性别的差异从二年级开始出现。与成年人类似，SGR至少在2年级时就将元音空间划分为高、低、前和后区域。平均而言，TCD与元音高度相关，TCP与元音前部相关。在我们的研究中，儿童使用不同的发音配置，以实现类似的声学目标。
In this paper, we study speech development in children us-ing longitudinal acoustic and articulatory data. Data were collected yearly from grade 1 to grade 4 from four female and four male children. We analyze acoustic and articulatory properties of four corner vowels: /æ/, /i/, /u/, and / A /, each occurring in two different words (different surrounding contexts). Acoustic features include formant frequencies and subglottal resonances (SGRs). Articulatory features include tongue curvature degree (TCD) and tongue curvature position (TCP). Based on the analyses, we observe the emergence of sex-based differences starting from grade 2. Similar to adults, the SGRs divide the vowel space into high, low, front, and back regions at least as early as grade 2. On average, TCD is correlated with vowel height and TCP with vowel frontness. Children in our study used varied articulatory configurations to achieve similar acoustic targets.
