Procedure and arrangement for transmitting a voice message

Abstract

The invention relates to a transmission method and a transmission arrangement capable of transmitting a voice message from a transmitter-side voice input unit (6) to a receiver-side voice output unit (13). The input voice message (SN.E) is converted into a voice message signal (SS.E), the voice message signal is transmitted via a transmission channel (Ü), and the transmitted voice message signal (SS.A) is converted back into a voice message (SN.A) and output. The transmission channel (Ü) comprises a signal processing unit (20, 21), a transmitter-side radio device (7), and a receiver-side radio device (17). Prior to transmission, an adjustment procedure is performed in which a measuring and adjustment unit (22) generates a test signal (TE), which is transmitted in the transmission channel (Ü) and then transmitted back to the measuring and adjustment unit (22).The measuring and adjustment unit (22) evaluates the quality of the transmission channel (Ü) and, if necessary, changes a parameter value (PW) of the signal processing unit (20, 21). The two radio devices (7, 17) do not require adjustment.
