<p>Apparatuses (101, 201, 301), method and systems (100, 200, 300) in accordance with the present invention provide for a visual display of speech, such as the visual display of a received audio signal in telecommunications, especially useful for the hearing impaired. The preferred apparatus embodiment includes a network interface (110), in which the network interface is coupleable to a first communication channel for reception of a first audio signal to form a received audio signal; a radio frequency modulator (270) to convert a baseband output video signal to a radio frequency output video signal and to transmit the radio frequency output video signal on a second communication channel for video display; and a processor arrangement (130) coupled to the network interface and to the radio frequency modulator, with the processor arrangement (130) responsive, through a set of program instructions, to convert the received audio signal to a text representation of speech, and to further convert the text representation of speech to the baseband output video signal. The radio frequency output video signal, when displayed on a video display (225), provides the visual display of speech. The preferred embodiment may also include a speech generation subsystem.</p> |
