Original abstract

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 in the nostril at the end of the sinus nasal. However the jet must have appropriate properties particularly concerning the flat spectrum shape required, generated by the air leaving the jet and expanding. The spectra of the random noise generated by the jet stimulate the excitation of the vowel formants while the flowing air is a condition for generating the individual consonants.

Příspěvek se zabývá experimentálním buzením vokálního traktu. Externím zdrojem je stlačený vzduch z nádoby se stlačeným vzduchem. Vzduch je dopravován do nosních otvorů na konci nosní dutiny. Tryska musí mít vhodné vlastnosti, jež je schopna poskytnout ploché spektrum v poměrně širokém frekvenčním rozsahu. Spektra náhodného signálu pak budí formanty samohlásek a proudící vzduch je podmínkou pro generování souhlásek.
