Vowel Perception with Virtual Formants

This study examines the potential role of the auditory spectral integration in phonetic vowel quality decisions. Synthetic stimuli included a “virtual formant (F2)” which was produced by inserting two pairs of sine waves below and above a “perceptual target frequency” (the spectral center-of-gravity, COG). Intensity weighting across the pairs of sine waves created a virtual F2, i.e., an F2 perc...
