[Regulation of voice quality parameters at the beginning of phonation].
In 8 healthy probands, 6 patients with functional voice disorders, 3 singers and 3 deaf patients we studied the regulation of the voice parameters amplitude and fundamental frequency at the beginning of phonation. Analyses were performed under the following conditions: (1) normal conditions; (2) after troubling pharyngeal and/or glottic mucosal receptors by topical anaesthesia; (3) in the case of normal hearing during disturbance of the audiophonatory feedback mechanism by binaural masking, and (4) with a combination of the latter two situations. The results are discussed.
