Phonation basics
Question | Answer |
---|---|
adduct | move toward each other ending at midline |
abduct | move away from each other starting together at midline |
larynx | gateway to the respiratory tract |
larynx | breathing, protect airway, fixing thorax during activies requiring strong abdominal pressure |
vocal folds | serve as a valve between the speech tract and the respiratory tract |
vocal fold vibration is possible because | vocal folds are located within fixed larygeal framework |
vocal fold vibration is possible because | muscles within the larynx (intrinsic laryngeal muscles) facilitate vocal fold abduction and adduction |
vocal fold vibration is possible because | some of these intrinsic laryngeal muscles cause changes in the elastic properties of the vocal folds, affecting their rate of vibration |
vocal fold vibration is possible because | an outgoing airstream also affects vocal fold vibration |
