应用磁共振成像技术对129例2~25岁正常人的声道形态进行了定量研究。形态测量数据，包括正中矢状面声道的长度、形状和比例，使用计算机图形技术收集。声道长度与身体大小(身高或体重)呈显著正相关。这些数据还显示了男性和女性声道形态上的明显差异，包括整体声道长度以及口腔和咽腔的相对比例的变化。这些性别差异在儿童中并不明显，但在青春期出现，这表明它们是男性青春期声音重塑过程的一部分。这些发现对语音识别、语音取证和人类语音生成系统的演变具有重要意义。为今后人类声道形态和发育的研究提供了一个非本土标准。(C)1999年美国声学学会。[S0001-4966(99)02008-1]。
Magnetic resonance imaging was used to quantify the vocal tract morphology of 129 normal humans, aged 2-25 years. Morphometric data, including midsagittal vocal tract length, shape, and proportions, were collected using computer graphic techniques. There was a significant positive correlation between vocal tract length and body size (either height or weight). The data also reveal clear differences in male and female vocal tract morphology, including changes in overall vocal tract length and the relative proportions of the oral and pharyngeal cavity. These sex differences are not evident in children, but arise at puberty, suggesting that they are part Of the vocal remodeling process that occurs during puberty in males. These findings have implications for speech recognition, speech forensics, and the evolution of the human speech production system, and. provide a nonnative standard for future studies of human vocal tract morphology and development.
