声学语音学的声音学
临床语言学临床语言学

背景情况:

裂口口腔演讲通常涉及喉停止 (GS),影响理解能力.
需要采取客观措施来补充这一群体中GS的听觉感知评估.

研究的目的:

为了研究前声电声学信号 (PVES) 在表达喉停止 (GS) 在普通话说者与修复裂口的实用性.
评估PVES特征与GS的听觉感知判断之间的相关性.

主要方法:

分析了83名患者的1680个普通话发言,使用电图 (EGG).
基于对GS存在的听觉感知评估进行分类的发言 (A,B,C类).
使用MATLAB自动检测EGG信号中的PVES振幅和时间间隔.

主要成果:

EGG PVES发生率与听觉感知评价 (r=0.703,P<0.000) 显示出强烈的正相关性.
在不同组中观察到平均PVES振幅的显著差异 (P<0.05).
在A与B组和A与C组之间发现了PVES时间间隔的显著差异 (P<0.05).

结论:

Larynx

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
