Vowel is a speech synthesizer and formant oscillator. The module features two algorithms for generating sounds and word fragments based on the human voice. Knobs and CV inputs provide access to what Vowel is saying. The pitch of the resulting babbling can be varied from low baritone to high squeaking.
Vowel comes equipped with speech and FOF synthesis algorithms. The pitch can be adjusted via a potentiometer and a CV input. In addition, there are manually as well as voltage controllable Vowel and Formant parameters.
