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.

I’m too smart

After watching many YouTubers use this, I was excited to experience the same phenomenon! There is no song on the app, but I sang anyways. I found it makes me sing slower, which is not what I wanted! I did the tongue twisters, but these were even more boring because I was just reading it word from word. Only when I was sloppy and tried not to think at all did it make me annunciate less which was pretty funny. Maybe my headphones aren’t loud enough? They’re the ones that came with my iPhone 7, I feel like they should do the trick at full volume with my mouth on the mic. Mostly, I just ended up with a bunch of recording of me doing ridiculous tongue twisters, which isn’t what I wanted, but it’s still pretty funny lol. It is probably better when you do it with friends because your brain is more split when you know people are watching and reacting to you, so you’re probably more distracted.

****IF SPECIAL HEADPHONES are what’s required, this needs to be stated in the app description or at least when the app starts up.

I doesn’t work with Bluetooth...

It’s a great app but does not work with Bluetooth... so if you only have Bluetooth headphones/earbuds then this is not the app for you.

Tried to use this app with AirPods and it wouldn’t connect. Other apps were fine. Full screen Ads every 30 seconds make this app unusable and a blatant attempt at a money grab.
