Even though days of phone pranking are pretty much in the past, this device is still worth making. I am talking about a real-time Voice disguiser device that transforms audio input into the famous “robot voice”. Voice disguiser device Miami Beach Coral Gables.
Heart of this device is Holtek HT8950 Voice disguiser device which needs only a few external components and a power supply to work. The modulator can be built in handheld the box with a battery or as a desk sitting tool as shown in the picture. Voice disguiser device Miami Beach Coral Gables.

In TV ad campaign for Marks & Spencer, they use the Electric Light Orchestra track ‘Mr Blue Sky’. There’s a distinctive robotic vocal sound in it that I am curious about. How was it made? I was thinking at first that it was something like Auto-Tune (as on the annoying Cher single!) but the ELO record was made years before that. Or is it a remix? (I’m not old enough to remember the original!) Voice disguiser device Miami Beach Coral Gables.

The effect is created using a device known as a vocoder, which is short for voice encoder, though it was also briefly known as a ‘voder’. Like so many things in this business, the vocoder dates back many decades and, again like so many things in this business, is derived from telephonic communications technology! Voice disguiser device Miami Beach Coral Gables.
It was originally developed by Homer Dudley of Bell Labs in the ’40s as a means to compress audio for transmission down copper telephone lines. Later, one Werner Meyer-Eppler of Bonn University saw the potential for the vocoder in the then-emerging genre of electronic music. Voice disguiser device Miami Beach Coral Gables.
Basically, a vocoder has two inputs: a modulator and a carrier. The modulator is usually fed by a microphone, typically with sung or spoken words, and the carrier will take a bright, sustained synth sound. Chords are played into the carrier input and words are spoken (or sung) into the modulator. The spoken/sung words are electronically imposed on the carrier signal, to create the effect of the synth speaking or singing. So how does this magic work? Voice disguiser device Miami Beach Coral Gables.
The carrier signal is split into different frequencies, using very tight band-pass filters (not unlike those in a graphic equalizer), and each of these has a voltage-controlled amplifier or, more recently, a digitally controlled amp. Voice disguiser device Miami Beach Coral Gables. The modulator input is similarly split into different frequencies and on the output of each of the modulators’ band-pass filters is an envelope follower that opens and closes the corresponding amplifier on the carrier input (see diagram). Thus, if you were to say ‘ooaaah’ into the modulator, the lower filters on the modulator would activate and open the lower filters on the carrier’s signal; as the modulating signal moved into ‘aaaah’, the modulator’s higher filters would be activated, in turn opening the carrier’s upper filters and creating the illusion of vocals.

If several people wanted to use the Call Defender during a session, how would it be best to know what mode to use for each person.
