Now you can answer the telephone without anyone recognizing your voice. Press a button and completely change your voice. There are 8 different voice changing settings. A man can sound like a stranger, a women like a man, or a grand-dad like a child. Unlike most voice changers, the Voice Changer 2 connects to your handset, making it compatible with most telephones, even office phones. Travels anywhere, measures just 5" x 3" x 1/2"! Voice Changer II operates on 3 AA batteries and includes handset connector cable. TVC-2 Will not work on cordless phones or phones with dialing buttons on the handset.
