Abstract

THE OPERATION OF THE SEMI-AUTOMATIC SPEAKER IDENTIFICATION SYSTEM IS PRESENTED AND MODIFICATIONS TO THE SYSTEM ARE DESCRIBED, WHICH WOULD BE REQUIRED TO USE ITS CAPABILITIES FOR AUTOMATIC PERSONAL IDENTITY VERIFICATION. SPECIFIC APPLICATION AREAS FOR THE SPEAKER IDENTIFICATION TECHNIQUE ARE DISCUSSED, INCLUDING: IDENTIFICATION FOR CRIMINAL APPREHENSION, IDENTIFICATION FOR CRIME PREVENTION (PERSONAL IDENTIFICATION), AND NONCRIME-RELATED APPLICATIONS. THIS REPORT CONFINES ITSELF TO THE TECHNICAL REQUIREMENTS FOR SPECIFIC FUNCTIONS OF PERSONAL IDENTIFICATION FOR AREAS SUCH AS COMPUTER ACCESS SECURITY, AREA ACCESS SECURITY, IDENTITY VERIFICATION FOR CHECK AND CREDIT CARD USAGE, AND REMOTE IDENTITY VERIFICATION BY POLICE IN THE FIELD. THE PRINCIPAL TECHNICAL FACTORS ADDRESSED ARE VERIFICATION ACCURACY OF THE AUTOMATIC IDENTIFICATION EQUIPMENT, AND THE REQUIREMENTS FOR GENERATING AND MAINTAINING A DATA BASE OF INDIVIDUAL SPEECH CHARACTERISTICS FOR USE IN IDENTIFICATION APPLICATIONS.
