Plug in your earphones and try to talk. Batteries not included.
Reverb Speech Jammer works by playing your own voice back to you, slightly after you've said it. This will throw most people off and ruin your ability to talk impaired, hence "jamming". Note that you must have your headphones/earphones plugged in in order for it to work, and at a reasonable volume. It works best if you're trying to read something aloud, and its effects will vary from person to person and device to device (so please don't shout at me if it doesn't work for you).
