Speech Zapper now 50% off!! (originally $1.99) with absolutely no in-app purchase or ads.

Speech Zapper works on the same principal as the ig nobel awarded speech jammer gun.

Have you ever wanted to silence someone? Probably your over-talkative friends, spouse, or in-laws. Speech Zapper can help.

Speech Zapper exploits mental loophole that will confuse the target's brain so that he/she has to stop talking, without any physical discomfort.

Speech Zapper utilizes psychological finding that when you hear your voice played back to you with a delay of a fraction of a second you will start stuttering and eventually have to stop speaking. The effect is what psychologists call Delayed Auditory Feedback (DAF). It is normally used to help patients with stuttering problem talk normally, but when used on normal person it make it almost impossible for the person to talk.


1)Aim your device at your target (or put on your headset)
2)Push START
3)Adjust delay, make sure it's loud enough you only hear delayed voice; use volume boost if needed

Warning: You need a headset/headphone or directional speaker for Speech Zapper to work properly


1.Directional speak is needed to ensure maximum effectiveness, but is not required
2.Speech Zapper will not work against meaningless speech such as "ahhh!" or "Ooh!"
3.Speech Zapper work psychologically using delayed auditory feedback principal, so, the target can force it out
