An apparatus and device for permitting a person with a tracheostomy to speak while being ventilated. A tracheostomy tube having an orifice in its tubular wall and a valve means in operative association with the orifice are provided. A valve controlling means is arranged to cause the valve means to block the orifice when a ventilator which is connected to the tracheostomy tube feeds inhalation oxygen thereto, and to open the orifice when exhalation occurs, thereby allowing exhaled breath to flow upwardly in the trachea past the larynx to permit speech. The valve means may comprise a balloon mounted inside of a hood.
