Abstract: A voice command control and verification system and method stores for each authorized user, one or a series of speech models of 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 of the corresponding voice command. Each user has a means of asserting his or her claimed identity to the system, preferably without an overt action such as the entry of digits. When an identity is asserted, and a voice command is thereafter spoken by a person, the system first matches a model of the voice command against the stored models for the user having the claimed identity.

Abstract: An individual's speech sample, obtained for the purpose of speaker verification, is used to create a "protected" model of the speech. The protected model, which is stored in a database in association with a personal identifier for that individual, is arranged so that the characteristics of the individual's speech cannot be ascertained from the protected model, without access to an encryption key or other secured information stored in the system.
