Electroglottography is non-invasive method of measuring vocal fold contact during voicing without affecting speech production. The  Electroglottograph (EGG) measures the variation in impedance to a very small electrical current between the electrode pair placed across the neck as the area of vocal fold contact changes during voicing. This two-channel Electroglottograph, model EG-2-PC, provides simultaneous EGG Waveforms at the neighboring neck location allowing correct electrode placement and verification of waveform accuracy. Using this patented multichannel approach not only makes the technique easier to use and more reliable, but also can allow the quantitative measurement of vertical laryngeal movement during voicing.

This EGG works  with  Vocal Assessment. Simply plug the cable into your sound card and record the signal via the electrodes or microphone.
