In 1973 Kaegi published some of the results of his early research in Interface. In this article you can clearly see the data reduction of recorded signals, which has no major influence on the recognizability of the sound, in this case a spoken vowel /a/.

In 1974 in the second part of the article Kaegi explores also fricatives and plosives, describing his early duplications in detail.

In 1978 Werner Kaegi and Stan Tempelaars published VOSIM for the first time under this name in the famous Journal of the American Audio Engineering Society. This is the main article at that time, in which the VOSIM model has been described in detail.

Stan Tempelaars, who was physicist and close collaborator of Werner Kaegi at Sonology had developed an impressive sound processing package (at that time not commercially available), which was used to make detailed FFT spectra of the sounds Kaegi analyzed and duplicated. Tempelaars published in 1977 an article in Interface about the theoretical VOSIM spectrum.

In 1986 Kaegi published a series of articles together with members of the MIDIM-group. This booklet was later jokingly called "The MIDIM-bible":
