Abstract

The purpose of this study was to develop a method for visualizing and assessing the characteristics of vowel production by measuring the local density of normalized F and F formant frequencies. The result is a three-dimensional plot called the vowel space density (VSD) and indicates the regions in the vowel space most heavily used by a talker during speech production. The area of a convex hull enclosing the vowel space at specific threshold density values was proposed as a means of quantifying the VSD.

摘要

本研究的目的是开发一种方法，通过测量归一化F1和F2共振峰频率的局部密度来可视化和评估元音发音的特征。结果得到一个名为元音空间密度（VSD）的三维图，它显示了说话者在言语产生过程中最常使用的元音空间区域。有人提出，以特定阈值密度值包围元音空间的凸包面积作为量化VSD的一种方法。
