Abstract

Un aparato para producir una voz similar a la voz humana en respuesta a datos digitales de excitación y a datos digitales de coeficiente de filtro, estando caracterizado dicho aparato por: (a) una primera memoria para almacenar dichos datos de coeficientes; (b) un circuito multiplicador; (c) primeros medios de circuito que acoplan dicha memoria y dicho circuito multiplicador; (d) un circuito aritmético que tiene una entrada acoplada a dicho circuito multiplicador; (e)una segunda memoria para almacenar datos procedentes de dicho circuito aritmético; (f) segundos medios de circuito para acoplar selectivamente las salidas de dicha segunda memoria y dicho circuito aritmético a una entrada de dicho circuito multiplicador; (g) medios de convertidor acoplados a la salida de dichos medios de memoria para convertir de valores digitales en señales analógicas datos seleccionados almacenados en dicha segunda memoria; y (h) una bobina vocal para convertir dicha señal analógica en sonido.
