Abstract: A speaking device may be fitted to a user's mouth or mouth and nose and sealed against the user's face in order to provide a sealed airspace for oral communications while underwater. The speaking device is collapsible while not in use and may be extended prior to use in order to provide a larger volume of sealed airspace in which the user can communicate. When extended and fit to the user's face an exhalation of air may be used to purge water from the device interior via a distal regulator port and allow for brief communication. Alternately, an air regulator may be coupled to the regulator port to aid in purging water and/or provide breathable air for prolonged communication. Alternately, an LPI line may be connected to an LPI port of the device and operated to aid in purging water and/or provide breathable air for prolonged communication.
