1. Method for generating a signal which corresponds to the degree of opening of the vocal folds of the larynx, in which the vocal folds are illuminated by means of a light source and are optically observed by means of an endoscope and a signal which is modulated by the movement of the vocal folds, the vocal fold signal, is displayed and/or recorded, wherein the vocal folds are illuminated with light having a wavelength greater than 600 nm or with red light, and in that the light which is modulated by the movement of the vocal folds, the vocal fold light, is received by a sensor and is detected in order to generate a vocal fold signal which can be visualised, wherein visible light which contains little infrared or red light is used at the same time to observe the vocal folds.
