Portable telephone voice changer

The portable telephone voice changer is an effective tool for maintaining telephone privacy.

Powered by a normal 9VDC PP3-type battery, it is slightly larger than a pack of cigarettes and allows voice modification on 8 different levels (four high and four low) plus a robotic tone.

Operation is very simple: just turn on the device, select the desired type of voice modification using the appropriate buttons, place the voice changer on the microphone of the telephone handset and speak through the device itself; your voice will be modified in real time and reach the microphone of the handset as well as the called/calling party on the other end of the line.
