Abstract
Abstract A method for dialing a telephone, using voice recognition to initiate the dialing and to determine the correct telephone number. The dialing is initiated with a spoken dial command that is recognized by using speaker independent templates that are stored locally with respect to the caller's telephone. The correct telephone number is recognized by using speaker dependent templates that are downloaded from a central database or by using speaker independent templates stored locally.
