Speech Jammer Pro

By Vu Tran

Open iTunes to buy and download apps.


EDIT: For those of you messaging me that the app does not work properly, YOU MUST use headphones that has a MICROPHONE INPUT with this app. For best results, it's recommended you use your Apple headphones.

The best speech jammer app available. It has an auto calibration feature and manual calibration for the feedback delay in order to fine tune the speech jammer.

Try it out! It really works.

What's New in Version 1.3.2

- Fixed delay function for some older devices

Works as Advertised

This app works great and allows you to record for extra laughs. I manual adjusted to 175ms like some sources mentioned as the mean for causing stutter. The best part, no ads!

However, please consider allowing playback through the phone speaker.


I did the auto calibrate and it was perfect. I tried the ABC's and so did my parents and grandparents yet no one could sing it successfully. It was well worth the 99cents and so was every laugh the app caused. Thanks and keep the good work coming


Highly recommend
