[Detection of latent velopharyngeal hyperfunction with the Lombard trial].
If subjected to Lombard conditions several patients with voice disturbances (17,7%) react by producing hyponasal speech which can be proved sonagraphically. The reason for this effect seems to be a habitual velopharyngeal hyperfunction, manifesting itself during bilateral deafening, while kinesthetic and reflectory mechanisms compensate for the auditory feedback loss. The deafening procedure using the Lombard effect can therefore be useful for diagnosis of functional components of voice disorders as well as in the therapy of functional voice disturbances.
