磁共振成像等观察技术的最新发展使我们能够获得对声道形状的准确描述。因此，在平面波传播的假设不成立的较高频率下，对三维声道的声学特性进行分析是可能的。简要介绍了历史上和传统的一维声道模型，然后介绍了三维声道声学特性的最新知识。
Recent developments in observation techniques such as magnetic resonance imaging allow us to obtain an accurate description of the vocal-tract shape. It is thus possible to perform analyses of the acoustic characteristics of three-dimensional vocal-tracts at higher frequencies where the assumption of plane wave propagation does not hold. Historical and conventional one-dimensional models of vocal-tracts are briefly described followed by recent knowledge of the acoustic characteristics of three-dimensional vocal-tracts.
