Abstract

Procedimiento para el funcionamiento de sistemas asistidos por voz, como dispositivos de comunicación y/o dispositivos de intercomunicación en automóviles, en el que se reciben señales de voz y señales de ruidos de fondo como señales totales a través de una disposición de micrófono múltiple (M 1, M 2) y se transmiten al menos a un altavoz (L 1, L 2), donde la señal total recibida por el micrófono (M 1, M 2) respectivo es desplazada en la frecuencia en primer lugar en un valor absoluto F y a continuación es transmitida ya al o a los altavoces (L 1, L 2) o a la entrada de un dispositivo controlado por voz, caracterizado porque para la eliminación de reacoplamientos y señales de eco, se resta de la señal total no desplazada todavía en la frecuencia de un primer micrófono (M 1, M 2) la señal total desplazada en el valor absoluto F de otro o de un segundo micrófono (M 2, M 1), y a la inversa.
