摘要：
A patient interface of a respiratory therapy system is provided, and comprises: a. a mask body； b. a mask seal secured to the mask body and configured to form a seal with the user's face, at least around the user's mouth； the mask body and mask seal being arranged to define an interior breathing chamber of the patient interface； and c. an inlet to the breathing chamber configured to receive a flow of breathable gases into the breathing chamber. To assist in allowing a user to speak clearly whilst wearing/using the patient interface, a user actuatable speech valve is provided on the patient interface and is operable to selectively occlude and open a speech flow path from the breathing chamber to atmosphere when the user wishes to speak.
