PURPOSE
The current study aimed to profile vocal fold morphology, vocal fold symmetry, gender and task-specific data for vocal fold length (VFL) and vocal fold displacement velocity (VFDV) in young normophonic adults in the age range of 18-30 years using ultrasonography (USG).
METHODS
Participants underwent USG across quiet breathing, /a/ phonation and /i/ phonation tasks, and acoustic analysis was conducted to explore the relationship between USG and acoustic measures.
RESULTS
The study found that males have longer vocal folds than females, and overall greater velocities were observed in /a/ phonation, followed by /i/ phonation, with the lowest velocity observed in the quiet breathing task.
CONCLUSIONS
The obtained norms can be used as a quantitative benchmark for analyzing the vocal fold behavior in young adults.
目的
本研究旨在使用超声（USG）对 18-30 岁的年轻正常发音成年人的声带形态、声带对称性、性别以及声带长度（VFL）和声带位移速度（VFDV）的任务特异性数据进行分析。
方法
参与者在安静呼吸、/a/发音和/i/发音任务中接受 USG 检查，并进行声学分析以探究 USG 与声学测量之间的关系。
结果
研究发现，男性的声带比女性长，总体上在/a/发音时观察到更大的速度，其次是/i/发音，在安静呼吸任务中观察到的速度最低。
结论
获得的正常数据可作为分析年轻人声带行为的定量基准。
