After a brief departure onto a couple of other projects, I'm back to complete Project Mego--my 2XL-Google Assistant conversion--and I needed to come up with a way to change the voice from one of the stock Assistant voices to more of a robotic sound.So, I started playing with the Velleman MK171 Voice Changer Kit as a jumping-off point for my own voice modulator. I use an arduino board, a MEMS microphone breakout board, and an active speaker to implement my voice changer. It does this by shifting the frequency spectrum associated with the voice therewith, upwards or downwards in seven incremental steps and the resultant output is heard as relatively much thinner or thicker in its frequency. If the voice is present or the microphone is on, the other signal gets off immediately to provide the microphone audio to the speaker. Here is a shield for Arduino 328's that solves this problem.
