Vowel identification depends on formant peaks being representable in the output spectrum.

Evidence

The representation of the formant structure in the output spectrum is important if the listener is to identify different vowels. Figure 4.38 suggests that somewhere between the G above middle C and the G an octave above, Table 4. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1368
