A-129 /5

Voiced/Unvoiced Detector

$ Unvoiced Input

This unvoiced carrier signal input $ is used to patch

in the sound source you wish to use for the carrier

signal for unvoiced sounds.

As a rule, you'd tend to use the output from a noise

module (A-117, A-118), a high-frequency sawtooth

wave, or the 6 Oscillator output from an A-117 mo-

dule.

% Voiced Input

This voiced carrier signal input % is used to patch in

the sound source you wish to use for the carrier

signal for voiced sounds.

Usually, you'd tend to find a low-mid frequency VCO or

mix of several VCOs doing this job.

& Voiced / Unvoiced Output

Depending on the status of the voiced/unvoiced detec-

tor switching, output & relays the input signal from

socket $ or %.

Vocoder block diagram including A-129 /5

The way the A-129/5 should be patched into the whole

vocoder system is shown in fig. 2 (see next page).

Smoothing Voiced / Unvoiced transitions

Whereas the A-129/5's internal switch produces an

abrupt change from voiced to unvoiced carrier and

vice versa, it's possible to patch the gate output to a

slew limiter, invert one of the carrier VCAs, and pro-

duce a smooth transition.
