Abstract: A message initiated at a first terminal and transmitted over a first communications link to a relay interface may be relayed to a second terminal over a second communications link by converting the words in the message received at the relay interface into a format compatible for use by the second terminal. Then, the formatted words are individually analyzed so that corrections may be made prior to display at the second terminal. The formatted words may be corrected manually by a relay agent or automatically utilizing a computer program associated with a relay terminal at the relay interface. Then, the analyzed words are displayed at the second terminal. The relay interface may be used for unilateral and bilateral communication between a standard telephone set and a telecommunications device for the deaf (TDD).
