摘要/Abstract

摘要：

该文研究关于人体声道形状确定的反问题, 旨在由嘴唇处所有正频率的绝对声压或嘴唇处声压函数在复平面内的极点分布, 来重构人体声道半径, 证明两个唯一性定理, 并给出相应的重构算法.

Abstract:

In this paper, we study the inverse problems for the determination of the shape of a human vocal tract, which consist in recovering the radius of a human vocal tract from either the absolute sound pressure at the lips at all positive frequencies or the poles of the sound pressure at the lips in the complex plane. Two uniqueness theorems are proved, and the corresponding reconstruction algorithms are provided.

Key words: Inverse problem, Speech acoustics, Sturm-Liouville operator, Scattering of vocal tract
