Think you're a smooth talker? Turn on the free Speech Jammer and you'll be surprised. Speech Jammer slightly reduces the rate at which you hear your voice, making it very difficult (or impossible) to talk. The more you spontaneously and continuously talk with the Speech Jammer, the harder talking becomes.

The humour from one person experiencing the Speech Jammer will quickly spread around the room, but the effect has to be experienced first-hand.

Speech Jammer offers
• Adjustable delay to impair speech
• Tongue twisters to make it even more difficult
• Ability to record Speech Jammer sessions
• Share recordings with friends via iMessage, Text, E-Mail, Facebook, Twitter, copied link or iTunes
• Offers short-cuts to common functions using 3D Touch Quick Actions on the home screen

Speech Jammer works best with noise cancelling headphones, and headphones with the microphone built-in. If you cannot get proper results, try adjusting the slider. Wired headphones are required.

This app is pretty funny, and me and my friend were trying to say stuff, but after a few minutes I started feeling wierd like I was on happy gas, and like I was going to pass out. It may be just me, but if not, I advise not using this more than a few minutes.

So I’m kind of person that likes to download random at home in the bathroom because I’m bored so I saw a girl on TickTock is it and I thought oh what a good idea I want to try this and after a few times I could hear everything you know everything is delayed just how I like it supposed to work I could hear my brother is yelling in the background and then it said speech jammer want to open SHEIN which. As a clothing app that I have and I haven’t used it for so long so of course I would have taken me the page that this app took me too. So I haven’t been on in forever but once it took me app it immediately took me to pictures of Lingerie and bikinis! I do not recommend getting this app if you don’t want to see uncomfortable images!
