基于嘴唇处的声压数据确定人体声道半径

Abstract

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

CLC Number:

O175.8
