The invention relates to ECG (electroglottograph) measuring method and device for vocal cords. The method includes the steps of firstly, coating the surface of an electrode plate to obtain a contact layer; secondly, tightly attaching the electrode plate to a vocal cord position on a neck; thirdly, fixing the electrode plate, allowing a testee to make voice, and outputting vocal cord signals from an audio output end after being processed by the electrode plate and the ECG measuring device. 2MHz signals are applied to thyroid cartilage to apply high frequency excitation to a throat so as to eliminate external interference from myoelectricity, a microphone and the like. The signals of the electrode are measured and are subjected to bandpass filtering, a detecting circuit and bandpass filtering to obtain corresponding impedance changes. Vocal cord vibration is reflected by contacting the electrode with throat and measuring electrical characteristic changes of a volume conductor at the throat.
