语音产生过程中声道行为的建模需要对整个声道进行精确测量。为了实现这一点，在0.5 T系统上使用定制的双环环绕线圈进行磁共振（MR）成像。在持续生产五个美国英语元音的过程中，从声门到嘴唇的区域的正中矢状面成像。使用梯度扰相梯度回波序列实现4秒成像时间。图像清晰地显示了整个声道的轮廓，并表现出元音产生的基本发音特征。能够以1 mm分辨率测量沿声道沿着不同点的正中矢状宽度。这些测量结果被用来构建一个管道模型，用于预测声道的声输出。得出的结论是，无风险的MR成像有望成为一种重要的手段，获取数据的声道建模，应用语音病理学，语言学和人工语音。
Modeling of vocal tract behavior during speech production requires accurate measurements of the entire vocal tract. To accomplish this, magnetic resonance (MR) imaging was performed on a 0.5‐T system with a custom‐made, double‐loop, wraparound coil. A midsagittal section of the region from the glottis to the lips was imaged during sustained production of five American English vowels. A gradient‐spoiled gradient‐echo sequence was used to achieve a 4‐second imaging time. Images showed clear profiles of the entire vocal tract and exhibited essential articulatory features of vowel production. It was possible to measure midsagittal widths at various points along the vocal tract with 1‐mm resolution. The measurements were used to construct a tube model for prediction of the acoustic output of the vocal tract. It is concluded that risk‐free MR imaging promises to be an important means of acquiring data for vocal tract modeling, with applications to speech pathology, linguistics, and artificial speech.
