It is attempted to reduce the phonetic quality of vowels to the positions of the peaks in their tonotopical spectra relative to the other peaks, simultaneous or preceding in context. Synthetic two-formant vowels were identified by speakers of languages that differentiate richly among high vowels (Swedish, Turkish). The parameters F1 (204-801 Hz) and F2' (509-3702 Hz) were systematically varied in steps of 0.75 critical bandwidth. F0 was kept close below F1 in all vowels. These were presented in two orders with subsequently rising or falling F2'. Most subjects heard predominantly close vowels. The "isophones" of most subjects could be described in a uniform manner implying a normalization with respect to two reference points, one at a distance of 3 critical bands above F0 and the other one at an absolute position corresponding to 2.8 kHz. It is speculated that this second reference point might represent a default position of the third formant or the like.
