Speech Jammer FAQ
How is this generator supposed to be used during a conversation?
Play it louder than your voice, then speak quietly and very close to the other person so they hear you over the sound.
How does its sound differ from white-noise jammers?
It uses a speech-like sound buried under severe distortion, which is described as difficult to filter out or recover.
