摘要： In order to solve the problem of providing a speaking valve which is of simple construction and which is inexpensive to produce, a speaking valve (1) is proposed which has a cover part (2), a controller (3), a housing part (5) and a filter (8), wherein the housing part provides a valve seat arranged proximally therein, wherein the controller comprises a closure part (4), and wherein the closure part cooperates with the valve seat when the speaking valve is moved from an open position into a closed position, wherein the cover part is formed at least partially of an elastic material, wherein an at least partial deformation of at least one region of the cover part takes place as a result of the speaking valve being moved from the open position into the closed position, and wherein the filter is arranged on the controller in such a way that the filter can substantially follow the movement of the controller.
