Abstract: Provided is a laryngeal stroboscope using voice signals. The laryngeal stroboscope includes a photography unit for photographing a patient's vocal cords and a light source for illuminating a part to be photographed, a microphone for sensing the patient's voice, a high-pass filter for passing voice signals of 100 Hz or more among voice signals output from the microphone, a low-pass filter for removing signals of harmonic components from the voice signals output from the high-pass filter and passing only a voice signal in a fundamental frequency band, a peak detector for detecting a peak of the voice signal output from the low-pass filter and obtaining a pitch, and a controller for controlling the light source to intermittently emit light in response to a signal output from the peak detector and controlling the photography unit to operate according to whether or not the light is intermittently emitted.
