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.

    Had no problems with installing or running the app unlike many others have commented. Have not run into any of the dreaded ads that others refer to either, but I can guess how incredibly loud and annoying they would be, because the volume of the delayed playback is INCREDIBLY low, prompting you to crank the volume all the way up! I turned the volume on my headset all the way up, but the echo effect was completely drowned out by my real-time voice. Therefore, I did not experience much if anything in terms of slurring, stuttering etc. I think it would work A LOT better if the volume of the delayed sound was louder.

    Functional speech jammer that couldn't be more simple and easy to use. Try 100-200 ms for wired headphones, maybe even shorter for bluetooth headphones, and a medium to high sound level, for the jamming to be effective.

    Doesn't jam speech because it doesn't play back with a delay it just loops everything into a jumbled mess and gets really loud.

    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, however as I am not a physicist, I couldn't tell what pitches I was seeing, however I could see it was there. So if you are a musician, and you want a more physical side of your sound, whether it be instrumental or vocal, give it a shot, I'll be trying my trumpet soon, to see the results.

    Ok, so I gave stars because I could hear myself talking, but it had no effect on my speech. I was able to successfully talk normal, and basically over the feedback. I did read someone else's review that mentioned it doesn't work on everyone. Kind of bummed, because I was hoping to make a funny video with the jammed up effect and messed up speech. So, others beware, you may not end up with desired effect.
