Tentamen resolvendi problema ab Academia Scientiarum Imperial Petropoitana ad annum 1780 public propositum. 1) Qualis fit natura et character sonorum litterarum vocalium a, e, i, o, u tam insigniter inter se diversorum. 2) Annon construi qutans instrumenta ordini tuiborum organicorum, sub termino vocis humane noto, similia, quae literarum vaclium a, e, i, o, u sonos exprimant.

St. Petersburg, Russia: Typis Academiae Scientiarum, 1781.

In the first part of this work Kratzenstein described how the vowels could be produced in the vocal tract. In the  second part he described the construction of a new kind of organ with pipes for each of the vowels. Each pipe had a characteristic resonant cavity which should emulate the vocal tract for the corresponding vowel. In order to excite these resonators he made use of free reeds which at that time were little known. Kratzenstein demonstrated this instrument in Saint Petersburg in 1780; it was damaged and disappeared shortly afterwards. Digital facsimile from at this link.
