Summary
This study presents a novel computer analysis system for vocal fold vibration. The system uses color intensity differences to measure vocal fold movement in various voice disorders.
Area of Science:
- Laryngology
- Medical imaging
- Voice analysis
Background:
- Assessing vocal fold dynamics is crucial for diagnosing voice disorders.
- Stroboscopic videoscopy is a common tool for visualizing vocal fold vibration.
- Objective quantitative analysis of vocal fold motion remains a challenge.
Purpose of the Study:
- To introduce a new computer-analyzing system for evaluating vocal fold vibrations.
- To enable objective measurement of vocal fold excursion and glottal dimensions.
- To aid in the diagnosis and understanding of various voice disorders.
Main Methods:
- Utilizing a stroboscopic videoscope to capture moving picture frames of vocal fold vibrations.
- Developing a computer-analyzing system based on color intensity discrimination between sequential videoscopic images.
- Computing and displaying glottal transverse diameter and glottal area as a function of time.
Main Results:
- The system successfully discriminates between sequential videoscopic images using color intensity.
- The system enables measurement of the excursion of the right and left vocal folds.
- Quantitative data on glottal transverse diameter and glottal area over time are generated.
Conclusions:
- The developed computer-analyzing system offers a useful method for objective vocal fold analysis.
- This technology can enhance the diagnostic capabilities for voice disorders.
- Further application of this system can improve understanding of vocal fold biomechanics.
