在声道建模领域已经有相当多的研究工作，但是关于声道形状的直接3D测量的信息仍然非常少。本研究的目的是获取，使用MRI，库存的三维声道气道形状，对应于一组特定的元音和辅音。对3D形状进行分析，以找到沿着从声门延伸到嘴的中心线的横截面积，以产生“面积函数”。这些面积函数然后被用作输入到声道中的1D声波传播的计算机模型。最终的结果是模拟从口腔辐射的语音波形，并且与从同一受试者记录的语音波形非常相似。
There have been considerable research efforts in the area of vocal tract modeling, but there is still a very small body of information regarding direct 3D measurements of the vocal tract shape. The purpose of this study was to acquire, using MRI, an inventory of 3D vocal tract airway shapes that correspond to a particular set of vowels and consonants. The 3D shapes were analyzed to find the cross-sectional areas along the centerline extending from the glottis to the mouth to produce an 'area function'. These area functions were then used as input to a computer model of 1D acoustic wave propagation in the vocal tract. The final result was a simulation of the speech waveform radiated from the mouth and closely similar to the speech waveform recorded from the same subject.
