基于频域数据的元音清晰度逆散射
Inverse scattering for vowel articulation with frequency-domain data
摘要：
分析了人体声道中元音发音的逆散射问题。当一个单位振幅，单色，正弦体积速度从声门向嘴唇发送，各种类型的散射数据被用来检查是否可以唯一地确定由每个数据集的声道的横截面积。在考虑的数据集是在放置在离嘴唇一定距离处的麦克风处测量的压力的绝对值，嘴唇处的压力，以及从声门到嘴唇的传递函数。在非唯一性的情况下，指示什么附加信息可以用于唯一确定。
英文摘要：
An inverse scattering problem is analyzed for vowel articulation in the human vocal tract. When a unit amplitude, monochromatic, sinusoidal volume velocity is sent from the glottis towards the lips, various types of scattering data are used to examine whether the cross sectional area of the vocal tract can uniquely be determined by each data set. Among the data sets considered are the absolute value of the pressure measured at a microphone placed at some distance from the lips, the pressure at the lips, and the transfer function from the glottis to the lips. In case of nonuniqueness, it is indicated what additional information may be used for the unique determination.
