Materials Part III - Ambiguous Correspondence between Vowels and Patterns of Relative Spectral Energy Maxima or Formant Patterns or Complete Spectral Envelopes

M9.2: Ambiguous Spectral Envelopes

For the frequency range relevant for the perceived vowel qualities in question, many of the sound series presented in the previous chapter do not only show similar patterns of vowel-related spectral peaks and similar patterns of calculated F1–F2 but also similar vowel-related spectral envelope shapes for sounds of different vowels, including similar patterns of calculated F1–F2–F3 for sounds of front vowels (for all calculated formant frequencies refer to the online digital version of the Materials).
