ABSTRACT:
Apparatuses, systems, and a method 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 includes a network interface that is coupleable to a first communication channel to receive an audio signal; a radio frequency (RF) modulator to convert a baseband output video signal to a RF output video signal and to transmit the RF output video signal on a second communication channel for video display; and a processor coupled to the network interface and to the RF modulator for running a set of program instructions to convert the received audio signal to a text representation of speech, and to further convert the text to the baseband output video signal. The RF output video signal, when displayed on a video display, provides the visual display of speech. The preferred apparatus may also include a speech generation subsystem.
