ABSTRACT:
A novel interactive telephone communication system and method are provided which allow a hearing-impaired person, using a TDD, to send and receive information over a conventional two-way telephone subscriber network without communicating directly with another person. The hearing impaired person communicates over the subscriber network with a TDD coupled directly or indirectly to the network. The automated processing system includes a receiving circuit coupled to the network to receive communication signals from the hearing-impaired caller and processing means for processing a received communication signal according to a predefined control matrix. The processing means includes retrieval means for selectively retrieving one of a plurality of separately addressed TDD displayable messages stored in an associated computer database. Transmitting means are also provided for sending a retrieved TDD displayable message to the callers TDD for display. Depending upon the embodiment, the communication signal received by the system can comprise either a conventional touch-tone type telephone signal, a rotary type telephone signal or a TDD (e.g., Baudot) coded signal. A related processing method is also disclosed.
