The easiest solution is to use USB for all three.Īfter prototyping using Raspberry Pi 4 and various USB devices, we settled on Raspberry Pi Zero W with a small USB mic and Pimoroni Speaker pHAT to save space. Your Raspberry Pi needs a method for listening, speaking, and printing.
We built a full ‘boxed’ project, but you can keep it simple if you wish. Not only can it replicate detecting banned words, but it also doubles as a handy voice-to-paper stenographer (if you want a more serious use). This tutorial shows you how to build your own version using Raspberry Pi, the Google Voice API, and a thermal printer. In the future of Demolition Man, an always-listening government machine detects every banned word and issues a fine in the form of a receipt from a wall-mounted printer.
In a memorable scene, he is repeatedly punished by a ticketing machine for using bad language (a violation of the verbal morality statute).
Technology plays a central role in the film, often bemusing the lead character. In the 1993 action movie Demolition Man, Sylvester Stallone stars as a 1990s cop transported to the near-future.
