Abstract

An interactive voice response calling system (1) for automatically dialling a plurality of telephone numbers includes database (10) containing records of dialling information for a dialling campaign. A dialler (20) translates the records i the database into dialling instructions. A calling unit (40) initiates a plurality of calls based on the dialling instruction An interactive voice response unit (30) is operably connected to the calling unit (40) upon verification by the calling unit (40) that the connected call is answered by a person. The interactive voice response unit (30) includes a natural language recognition engine that automatically determines the language of a person and responds in the determined language and storage for temporarily storing answers to the dialling campaign. The system further includes a voice print secure identification unit for verifying a voice of a subscriber, and a switch allowing the interactive voice response unit (30) to send information relating to a call to the dialler (20) for updating the dialling instructions.
