Try to talk while hearing your own voice at a slight delay!
The Voice Jammer adds a slight delay to the your voice which causes many people to stutter and stumble over their words and ‘jam’ their voice.
This a project I decided to make after hearing about a megaphone shaped device that does the same thing. I found PureData, an audio synthesis API tool that helped me create a delay in audio recording playback which resulted in stuttered speech, and we’re not just talking speech replayed with a stutter, it literally makes you stutter, due to how our brains work somehow. I’m not sure why it works, but I do know the results are hilarious.
