7th International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2011)
Recently, endoscopic high-speed
laryngoscopy has been established for commercial use
and constitutes a state-of-the-art technique to examine
vocal fold dynamics.
Due to the need of high sampling rates, a high amount of frames has to be considered for subjective assessment. Especially long phonation recordings produce several hundred megabytes of digital data.
We present a technique for visualizing these highspeed videos in a compact and intuitive form. The high-speed videos are therefore mapped to threedimensional cycle-based graphs representing a detailed visualization of vocal fold dynamics.
Index Terms. High-speed-laryngoscopy, visualization, vocal fold dynamics, voice assessment
