Abstract

EN UN SISTEMA DE VERIFICACION DE LA PERSONA QUE LLAMA, SE SUMINISTRA UN METODO PARA COMPENSAR LAS DIFERENCIAS EN LAS MUESTRAS DE VOZ OBTENIDAS DURANTE EL REGISTRO Y AQUELLAS OBTENIDAS DURANTE LA VERIFICACION DEBIDO AL USO DE TIPOS DIFERENTES DE MICROFONOS MEDIANTE EL FILTRADO DE AL MENOS UNA DE LAS MUESTRAS DE MANERA QUE LAS SIMILARIDADES DE LAS DOS MUESTRAS SE INCREMENTEN. LA MUESTRA FILTRADA SE UTILIZA DENTRO DE UN PROCESO DE CONCORDANCIA DE VERIFICACION DE LA PERSONA QUE LLAMA. SE HA DESCUBIERTO UNA COMPARACION DE DOS VIAS EN LA CUAL TANTO UNA MUESTRA DE VOZ DE VERIFICACION COMO UNA MUESTRA DE REFERENCIA SE FILTRA CON CARACTERISTICAS DE MICROFONO NO LINEAL TALES COMO LAS CARACTERISTICAS DE UN MICROFONO DE CARBONO. TAMBIEN SE HA DESCUBIERTO UNA COMPARACION DE CUATRO VIAS EN LA CUAL LAS PLANTILLAS PRODUCIDAS A PARTIR DE UNA VERIFICACION SIN FILTRADO Y LAS MUESTRAS DE REFERENCIA Y LAS PLANTILLAS PRODUCIDAS A PARTIR DE UNA VERIFICACION FILTRADA Y LAS MUESTRAS DE REFERENCIA SE COMPARAN PARA IDENTIFICAR ALGUNA CONCORDANCIA. SE DETERMINA ALGUNA PUNTUACION PARA CADA COMPARACION. LA COMPARACION QUE TENGA LA MEJOR PUNTUACION SE UTILIZA PARA DETERMINAR SI SE HA PRODUCIDO CONCORDANCIA.
