Cylon Voice

Robotalk from an ATtiny microcontroller

Published in issue 375, March 2008

Cylon Voice
A voice changer that emulates a so-called Cylon voice can be implemented with the help of a small microcontroller. Those of you who have watched the (recent or older) TV series of Battlestar Galactica will immediately know what we’re talking about. For the non-SF fans amongst you, this is a metallic sounding robot voice. The circuit can be used as a gadget, but was originally designed to show how a simple digital circuit could be used for audio processing.
