About Vocal Designer
Vocal Designer” human vocal modeling technolog
is a further evolution of the “vocoder.” Here’s a simple
ex
lanation of the vocoder
What’s a
ocoder
he “vocoder” was invented by the physicist H. Dudley in 1939 as a technology
or compressing a voice
communication signal. Subsequently, musical instruments based on this technology were developed,
llowing
ou to pla
melodies and harmonies using a human voice. O
course, the audio source can be

of the human voice, we’ll be talking about it in terms of how a human voice is produced.
I
we ignore di
erences o
loudness, pitch, and variation between individuals, the wave
orm produced by
our vocal cords is essentially identical regardless o
what you’re saying (e.g., “ahh” or “eeh”). We can distin
guish spoken or sung words because o
the various resonances (
ormants) created by our vocal tract (the
shape o
our throat and the movement o
the lar
nx and mouth) and additional sounds called “
ricatives,”
plosives,” and “sibilants” that are added in var
ing wa
s over time. The e ect of the waveform created b
the vocal cords actuall
has a rather minimal e ect on what the listener hears
A vocoder analyzes these time-varying changes, electrically synthesizes the
shape o
the throat and movements o
the mouth (the
ormant movements),
nd uses these
ormants to modulate a musical si
nal (the carrier) rather than
the waveform produced b
the vocal cords. The vocoder “voice” produced in
this wa
was closer to that of a robot in a science ction movie rather than the

ocal Designer uses cutting-edge modeling technology to bring about a revo-
utionary leap in the accuracy o
this synthesis, succeeding in generating a
human voice” that is incomparably more realistic and natural than the sounds
produced b
vocoders of the past.

Unlike on typical synthesizers, the volume is controlled by the mic. Use your voice to draw the curve. Using
your voice, you can produce a range o
