The 'center of gravity' effect in vowel spectra and critical distance between the formants: Psychoacoustical study of the perception of vowel-like stimuli
{{output}}
A two-formant synthetic vowel with closely spaced formants (F1 and F2 being fixed) can be made perceptually similar to a single-formant stimulus with F ★ = (F 1 + F 2) 2 by adjusting the A 2A 1- amplitude ratio of the formants. The critical distance between t... ...
