Abstract
A respiratory mask includes a body having an interior space that defines a plenum between the body and a face of the user when the user is wearing the mask. The respiratory mask also includes a voice transmittal feature in and contiguous with the body that has a voice transmittal membrane that is configured to vibrate in response to sound waves generated by the user such that the voice transmittal membrane transmits the sound waves from the plenum of the body to an ambient environment of the user. The voice transmittal feature thus enhances the intelligibility of a user's speech so that others may more clearly understand what the user is saying. For example, this may increase safety and efficiency in emergency response situations in which the use of a respiratory mask is required.
