A study was undertaken to explore the effects of fixing the mandible with a bite block on the formant frequencies of the vowels [i a u] produced by two groups of children aged 4 and 5 and 7 and 8 years. Vowels produced in both normal and bite-block conditions were submitted to LPC analysis with windows placed over the first glottal pulse and at the vowel midpoint. For both groups of children, no differences were found in the frequencies of either the first or second formant between the normal and bite-block conditions. Results are discussed in relation to theories of the acquisition of speech motor control.
一项研究旨在探究使用咬块固定下颌对两组儿童（4至5岁和7至8岁）发出的元音[i a u]共振峰频率的影响。在正常和咬块条件下发出的元音均进行线性预测编码（LPC）分析，窗口置于第一个声门脉冲处和元音中点。对于两组儿童，正常和咬块条件下第一共振峰和第二共振峰的频率均未发现差异。结合言语运动控制习得理论对结果进行了讨论。
