An electrolaryngograph measures vocal fold vibration via neck electrodes

Evidence

The f0 of each of the four singers was measured when they sang the set of exercises by means of an electrolaryngograph (Abberton et al., 1989), which monitors vocal fold vibration directly. It makes use of two electrodes that are placed externally on the neck at the level of the larynx. A small high-frequency electrical current flows between the electrodes that is higher when the vocal folds are in contact than when they are apart. Note that acoustic measurements could not be used for f0 measurement in this experiment for four singers since the recordings of each singer would be contaminated with the sound from the other singers. — David M.
