Almost all of the clinical methods to examine the vocal folds are visual in nature. Vocal fold vibration is one of the most rapid physiologic events that occur in the human body, and is not visible to the human eye. To view these movements, images must be recorded at high speed, and then showed for display. Previously introduced ""ultra-high-speed cinematography"" and ""stroboscopy"" do not show practical vocal fold vibratory cycle. Recently developed electo-glottography (EGG) signal provides a usual estimate of vocal fold contact during the glottal cycle. Photo-glottography (PGG) provides usual informations about events related to opening of glottis. Therefore, simultaneous recording of EGG and PGG signals may offer complementary information about vocal fold vibration. We devised our own model of photoglottograph and made a common assembly of PGG and EGG together.
