• What activity does one have to do to get the Audeo to work?

A person has to produce control signals that activate the muscles, in order for The Audeo to work. For example, if you try to move your tongue up and down, or your throat forward, muscle contractions will occur in the laryngeal muscles, which in turn will produce the required signal. With some practice, a user can intentionally produce these same signals without any visual indication of activity.
