Abstract
Una señal de voz (2) es sometida a un análisis de tracto vocal y la salida desde el mismo es analizada por una red neural (5). La salida desde la red neural es comparada por los parámetros almacenados en funcion de definicion de red (4), para derivar la medicion de calidad de la señal suministrada hacia la fuente (2). La funcion de definicion de red es determinada aplicando al aparato de procesamiento instruible una medida de percepcion de distorsion indicativa del grado hasta el cual la distorsion se ve perceptible para un escuchante humano.
