Lexicon: Electroglottograph (EEG)

The Electroglottograph (EGG) is a device used in voice research to measure and analyze the contact and vibration patterns of the vocal folds during phonation. It consists of electrodes that are placed on the throat to detect changes in electrical conductivity as the vocal folds come together and separate during vocalization. The EGG provides valuable insights into vocal fold closure, vibratory behavior, and voice quality. It is a powerful tool for understanding and studying vocal production and can aid in diagnosing and treating voice disorders.
