25 The apparatus for hearing impaired persons of the present invention compris es a telephone receptionist style headset which is to be worn by a speaker pers on 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 b e visible from the distance to these hearing impaired persons at any given time. Alternatel y, the camera could be shifted back over an ear of the speaker person, and a minor directe d toward the camera placed instead ahead of the speaker's mouth, for reduced weight of th e headset ahead of the teacher and therefore enhanced comfort by the speaker person.
