On demand language interpretation in a telecommunications system

摘要

Easily accessed and widely available language interpretation services are provided in a public switched telephone network by a common platform adjunct which automatically connects an interpretation services subscriber with a selected language interpreter associated with a language interpretation platform in the network. A subscriber dials, for example, an international telephone number which includes a code indicating that the call is an international call, a country code, a city code, and a local destination number. The ANI of the subscriber is detected and the call is routed to the adjunct which further verifies and validates the subscriber. The adjunct places a call through the public switched telephone network to the language interpretation platform. The call is answered either by an automatically preselected interpreter or by a human operator who causes the call to be manually transferred to a desired interpreter. The international call is completed to the destination and the calling subscriber, the interpreter, and the called party are bridged together.
