Abstract

EN LA FASE DE RECONOCIMIENTO, SE PROCESAN LAS SEÑALES PROCEDENTES DE UN SENSOR (10) PARA OBTENER PARAMETROS QUE SE COMPARAN CON LOS ALMACENADOS EN UN DICCIONARIO (16) EN LA FASE DE APRENDIZAJE A FIN DE RECONOCER LAS ESTRUCTURAS VOCALES PRONUNCIADAS POR EL USUARIO EN AMBIENTES RUIDOSOS. EL REGISTRO DE DICHOS PARAMETROS EN LAS FASES DE APRENDIZAJE Y RECONOCIMIENTO COMPRENDE LA FORMACION DE TRAMAS NUMERICAS (S(N)) DE LONGITUD PREDETERMINADA A PARTIR DE LA SEÑAL PROCEDENTE DEL SENSOR, LA TRANSFORMACION DE CADA TRAMA DEL CAMPO TEMPORAL AL CAMPO FRECUENCIAL PARA OBTENER UN ESPECTRO X(I) Y LA APLICACION DE UNA TRANSFORMACION INVERSA, DEL CAMPO FRECUENCIAL AL CAMPO TEMPORAL, SEGUN UNA MAGNITUD [X(I)] SUP, GA}}, DONDE [X(I)] REPRESENTA EL MODULO DEL ESPECTRO Y GA}, UN EXPONENTE ADECUADO, QUE PUEDE VARIAR DURANTE LA FASE DE RECONOCIMIENTO.
