According to some embodiments, an apparatus for oral-motor and oral pharyngeal exercise may include an at least partially flexible, collapsible chamber formed to fit within a patient's mouth. An aperture may be formed in a flexible surface of the collapsible chamber to allow gas to flow into and out of an interior of the collapsible chamber. Moreover, a substantially inflexible wall of the collapsible chamber may be located opposite the aperture. According to some embodiments, the substantially inflexible wall incudes a coupling portion affixed to the flexible surface of the collapsible chamber and having a cleaning opening (e.g., an opening for optional cleaning). A cap portion may be adapted to be removably attached to the coupling portion to seal the interior of the collapsible chamber when attached.
