Method and apparatus for assisting an optimized acoustic adjustment of the human vowel tract

摘要

A process for the support of the setting of the acoustic properties of hollow bodies, in particular a vowel tract, wherein an acoustic wave field consisting of a frequency or of a plurality of frequencies or frequency bands on or in the mouth is produced, the frequencies in the range of from 200 to 10 000 hz are used, wherein by the adjustment of the geometry of the vowel tract of a be intensified or attenuated the wave field, the resulting wave field is measured by means of at least one microphone, wherein the evaluation of the resonance condition via the change in amplitude and / or displacement of the phase position between the exciting and the signal representing resonating.
