 Vocal Designer is the timing 
at which you play the keyboard and vocalize into the mic. For phrases involving rapid passages,
it’s best to hold down the notes on the keyboard, and mark the rhythm using your voice

Taking advantage o

The human voice starts 
rom the “vocal cords.” Exce
t

the 
orce and the 
itch o
 the voice, and di
 erences between individuals,
the vibrational wave
orm produced by the vocal cords does not change
signi cantl
 even when di erent sounds (such as “aah” or “ooh”) are being
roduced. These sounds become intelligible as spoken words because of 
arious resonances produced b
 the vocal tract (i.e., changes in the shape
and structure o
 the throat and movements o
 the mouth) and time-varying
sounds known as “sibilants
” “
ricatives
” and “nasals.” The e
 ect o
 the wave-
orm produced by the vocal cords is relatively small

thesizes the changes in the shape of the throat and mouth (formant move

 using these formants to modulate a signal from a musical instru
ent (the carrier) instead o
 the signal 
rom the vocal cords. “Voices” produced b
 a vocoder in this 
way are typically closer to a robot in a science 
 ction movie than to any actual human voice.
