SpeechJammerLite (free!)

SpeechJammerLite is a simplified version of SpeechJammer working on your PC. You can experience "artificial speech disturbance" with Delayed Auditory Feedback.

All you have to do is to prepare a headset, wear it, tune the volume up, speak something and jam yourself! You can also use "JamTimer," a presentation timer that fires speech-jamming after a specified duration.

How to use


Use another headset with a better ear-sealing performance if you can not obtain enough results.

Note that the speech inhibiting effect varies greatly with the individual and with accustomization.


Ryoya KAWAI released an instrall-free SpeechJammer working on Google Chrome. Try it from here.


We found a critical bug on the Windows Phone version. So the release of this version is canceled.
