Abstract

UN METODO PARA PERMITIR A UN USUARIO ACCEDER A UNO O MAS SERVICIOS VIA RED TELEFONICA PRONUNCIANDO UNA PALABRA DE ACCESO COMIENZA POR EL ESTABLECIMIENTO DE AL MENOS UN VALOR DE UMBRAL PREDETERMINADO PARA SEÑAL DE VERIFICACION DEL LOCUTOR. PARA CADA CARACTER PRONUNCIADO DE LA PALABRA CLAVE, EL METODO GENERA UN CONJUNTO DE PARAMETROS USANDO UNA TRANSFORMACION DE CARACTERISTICAS DE VERIFICACION DE LA VOZ. TRAS LA ENTRADA Y VERIFICACION DE LA PALABRA DE ACCESO, LOS CONJUNTOS DE PARAMETROS SE EMPLEAN PARA GENERAR UNA SEÑAL DE VERIFICACION DEL LOCUTOR PARA LA PALABRA CLAVE (PASO 78). TRAS LA OCURRENCIA DE UNA CONDICION DE LLAMADA PREVISTA, EL VALOR DE UMBRAL PREDETERMINADO SE AJUSTA PARA INCREMENTAR EL NIVEL DE SEGURIDAD EN EL ALGORITMO DE VERIFICACION. SI LA SEÑAL DE VERIFICACION DEL LOCUTOR PARA LA PALABRA CLAVE TIENE UNA RELACION PREDETERMINADA RESPECTO AL VALOR DE UMBRAL AJUSTADO (84), SE ACEPTA (88) LA IDENTIDAD DEL USUARIO QUE EFECTUA LA LLAMADA. SI NO, EL USUARIO PUEDE SER PREGUNTADO (90)PARA RESPONDER A ALGUNAS CUESTIONES PERSONALES ANTES DE ACEPTARSE SU IDENTIDAD.
