What You Need To Know About™ Cancer of the Larynx
    Posted: 05/05/2003
Mechanical Speech

You may choose to use a mechanical larynx while you learn esophageal or TEP speech or if you are unable to use these methods. The device may be powered by batteries (electrolarynx) or by air (pneumatic larynx).

Many different mechanical devices are available. The speech pathologist will help you choose the best device for your needs and abilities and will train you to use it.

One kind of electrolarynx looks like a small flashlight. It makes a humming sound. You hold the device against your neck, and the sound travels through your neck to your mouth. Another type of electrolarynx has a flexible plastic tube that carries sound into your mouth from a hand-held device. There are also devices that are built into a denture or retainer and can be worn inside your mouth and operated by a hand-held remote control.

A pneumatic larynx is held over the stoma and uses air from the lungs instead of batteries to make it vibrate. The sound it makes travels to the mouth through a plastic tube.
