The explanation of SpeechJammer

Just try to talk with this app on, it won't be easy! 📢
NOTE: Please use headphones.

With SpeechJammer, you can literally "jam" someone's voice. Through the Delayed Auditory Feedback effect, the speaker will have trouble articulating while speaking, effectively inhibiting his or her speech!

To put it briefly, the effect occurs when you hear your own voice at a slight delay. Many people tend to start mumbling, and therefore "jamming" speech. Works best if you try to read something!

Please use headphones, because using this app on speakers would generate significant audio feedback. Using the app in a somewhat silent room also improves the jamming effect.

So insane how this hacks your brain. I started talking like a slow robot trying to only say words after I hear myself. Brilliant.

It's cool as it does to a certain extent mess up your speech, but as you move along, you start to get used to it. Also, it somewhat acts a tuner if you look at the sound wave, you can also see the overtones,...

This app is really fun had a blast messing w my brain. There are a few ads but it really isn't a big deal, and they're not long or obnoxious or hard to close. Well designed, fun to play with, would recommend!
