A voice command control and verification system and method stores for each authorized user, one or a series ol speech models ol voice commands or phrases uttered by the authorized user. Each speech model has an associated action component which specifies the specific action that the authorized user desires in response to the issuance ol the corresponding voice command. Each user has a means ol asserting his or her claimed identity to the system, prelerably without an overt action such as the entry ol digits. When an identity is asserted, and a voice command is thereafter spoken by a person, the system first matches a model ol the voice command against the stored models for the user having the claimed identity. II there is a match, so that the voice command can be uniquely interpreted as corresponding to its associated action component, the system then verifies the claimed identity ol the user by comparing the vocal characteristics contained in the same command with the vocal characteristics ol the stored model. Upon successfill verification, the command is executed in accordance with the associated action component. The user ol the system has thus issued only a single command to both operate the system and to verily his or her identity.
