Abstract | Objectives
To determine the physiological patterns in the vocal fold vibration between non-fatigued and fatigued voices using
high-speed laryngscopic imaging and quantitative analysis.
Methods
Twenty amateur singers aged from 18 to 23 years (mean = 21.2 years, s.d. = 1.3 years) with normal voice participated
in an extended singing task which induced vocal fatigue. Laryngscopic images of /i/ phonations using high-speed
imaging system were recorded were taken before and after the singing task. The quantitative High-Speed Video
Processing (HSVP) program was used to extract indices related to the antero-posterior dimension (length), transverse
dimension (width), and the speed of opening and closing.
Results
A significant change (reduction) in the glottal length to width ratio index was found after the singing task, presumably
due to vocal fatigue. This indicated either a significantly shorter (antero-posteriorly) or wider (transversely)
glottis following vocal fatigue physiologically.
Conclusion
High-speed imaging technique can be used to identify vocal fatigue by examining the configuration of the glottis
using quantitative analysis.
