Speech recognition of caller identifiers using location information

摘要

A speech recognition system recognizes a caller identifier received during a telephone call as a speech signal from a caller. The system generates a plurality of caller identifier choices from the speech signal and receives location information of the caller. The system includes a database on which is stored a plurality of caller identifiers indexed to a plurality of location information. The system queries a database based on the received location information and retrieves one or more caller identifiers from the database. The system then selects the recognized caller identifier from the plurality of caller identifier choices based on the retrieved one or more caller identifiers.
