title: Computer-aided emergency telecommunications for the deaf.
abstract: Computer-aided telecommunications provide deaf teletypewriter users with 24-hour toll-free access to emergency services. An interface and software link the deaf caller's teletypewriter (TDD) with a microprocessor by reducing and inverting voltage levels between the two devices. This system facilitates rapid transmission of linguistically controlled triage questions to meet the communication needs of deaf patients.
