The apparatus for hearing impaired persons of the present invention comprises a telephone receptionist style headset which is to be worn by a speaker person on her head, in the conventional way. This headset is equipped with a frontwardly extending support arm which carries at its front free end a miniature camera (and also optional microphone) targetting the speaker's mouth. The camera is linked by a wire to a transmitter having intrinsic power means, which transmits the images caught by the camera by means of a wireless signal to receivers located remotely of the transmitter, e.g. on students' desks in a classroom. The receivers decode the signal and retransmits the images to television screens. Thus, hearing impaired persons can observe the screens for performing lip-reading of the speaker person, so as to understand the conversation, even though the speaker's mouth may not be visible from the distance to these hearing impaired persons at any given time. Alternately, the camera could be shifted back over an ear of the speaker person, and a mirror directed toward the camera placed instead ahead of the speaker's mouth, for reduced weight of the headset ahead of the teacher and therefore enhanced comfort by the speaker person.
