Vowel Modification

Changing the articulation (shape) of a vowel (often higher in the pitch range) for optimized acoustic and physiologic function. As pitch ascends, its harmonic set rises, causing its changing frequencies to migrate through their inherent spectral tone color gradients; furthermore, as source harmonics move into and through vocal tract resonance peaks, their intensity rises and falls, changing their individual contribution to the overall, composite tone color and vowel percept. This is especially evident when harmonics rise into and through the first resonance (F1). Usually refers to intentional changes of vocal tract shape.[1]
