Speech recognition method of and system for determining the status of an answered telephone during the course of an outbound telephone call

摘要

A system for determining the status of an answered telephone during the course of an outbound telephone call includes an automated telephone calling device for placing a telephone call to a location having a telephone number at which a target person is listed, upon the telephone call being answered, initiating a prerecorded greeting which asks for the target person and receiving a spoken response from an answering person and a speech recognition device for performing a speech recognition analysis on the spoken response to determine a status of the spoken response. If the speech recognition device determines that the answering person is the target person, the speech recognition device initiates a speech recognition application with the target person.
