Auto actuatable switch, speech simulator and method for tracheotomized individuals

摘要

A method for simulating speech in a tracheotomized individual includes providing a source of compressed air, regulating the air pressure, and controlling the flow of air from the source between a condition in which airflow is stopped and a condition in which airflow is allowed in response to actuation by the individual. The air flow is supplied to a reed to vibrate it, and the resulting vibration-modulated air flow is introduced into the pharynx of the individual, permitting the individual to articulate audibly comprehensible speech. Apparatus for carrying out this method is also described.
