New Generation Voice Transformer - The Professional's Choice.
This unit is an entirely new generation of advanced voice disguise and transformation technology. The Voice Transformer gives you total and unparalleled control of timbre, tone, formant, reverberation, and pitch. No other unit on the market offers these exclusive features.

User Friendly Design
The user interface feature four slider controls that allow for precise real-time adjustments. The convenient "hands free" headset/microphone allows you to concentrate on your conversation and not the operation of the unit. You can store the exact settings of a particular voice in one of eight memories so you can change voices instantly, even in the same conversation without the other party ever knowing. You can effectively portray eight different people instantly, even with gender changes!

20-Second Installation
Simply remove your handset from your telephone, and plug the modular jack cable supplied with the voice transformer into the handset plug. That's it.

Since most people are unfamiliar with what the "formant" component of the human voice is, here are the details. Human voices consist of two components. One is fundamental waves that are pitch-sensitive and the other is non pitch-sensitive fixed harmonics. The harmonics components that change along with with vocal cords and with the physical shape of the vocal tract add distinctive characteristics to person's voice and are caller formants.

All of the other telephone voice changers on the market today strictly pitch shifters, not addressing the critical formant control component of the human voice. They change formants when they alter pitch, so the voice that are pitched higher sound like "Mickey Mouse" and voice that are pitched higher sound like "Mickey Mouse". With the Voice Transformer's pitch slider, you can control pitch independently, without making formants change, while its formant slider works to effectively control the vocal cords and shape of the vocal tract. So it can change a male voice into a female or even a child's voice, yet sound completely natural.

Made in Japan, unit comes complete with a quality hands free microphone/earpiece, Size: 7" x 6.5" x 2". (Not compatible with cellular phones, cordless phones, or dial-in-handset phones.)
