VOWEL FORMANTS DETERMINATION BY EXTERNAL VOCAL TRACT EXCITATION

The paper describes an experimentally verified method of the external excitation of the vocal tract. The external source is the compressed-air supply in this case, coming from an outer source, e.g. from a pressure vessel etc. The air is supplied by means of a jet which is placed out of the vocal tract. This situation does not disconcert or restrict the patient in any way. However the jet must have appropriate properties particularly concerning the flat spectrum shape required, generated by the air leaving the jet and expanding. The spectrum must be generated within the frequency range which is defined by the range of at least three formants of all the vowels.

Příspěvek se zabývá externím buzením vokálního traktu. Externím zdrojem tlakového vzduchu je tlaková nádoba. Vzduch je dodáván speciální tryskou do nosní dutiny.Tryska musí mít speciální vlastnosti se spojitým spektrem generovaného hluku. Spektrum musí obsahovat frekvenční složky takové, aby tryska byla schopna budit alespoň tři formanty sledovaných samohlásek.
