Method for the transmission of speech data from a sending party to a receiving party, wherein the sending party respectively is associated with a sending party computer and the receiving party is associated with a receiving party computer, while the two party computers (10x, 10w) are interconnected via a plurality of redundant communication servers (2a, 2b), characterized in that, - the sending party speech information is created and this speech information is divided by the respective sending party computer into individual, numerical speech data values (x), - data packets (X1,... Xn) from the sending party, each comprise at least one numeric speech data value (x), each of which is associated with at least a timestamp in the form of a consecutive number which determines the sequence of the individual speech data values (x) with respect to the speech data values of the other data packets - the data packets (X1,... Xn) of the sending party (1 x) are transmitted to the communication servers (2a, 2b) connected to the sending party computer, - further data packets (A1,..., An, B1,..., Bn) are created by each communication server (2a, 2b), each of which is associated with at least one speech data value (x) transmitted from the sending party computer, and at least a further time stamp (T'), wherein the value of the further time stamp (T') corresponds to the remainder of the time stamp divided by a predetermined constant positive integer N, wherein N is selected to be equal for all communication servers (2a, 2b), - wherein N is determined as follows: N > (t delay,max - t dela y,m i n) / t samp, - wherein t delay,max refers to the maximum delay time of a connection line between a sending or receiving party computer (10x, 10y, 10z, 10w) and a communication server (2a, 2b), - wherein t delay,min refers to the minimum delay time of a connection line between a sending or receiving party computer (10x, 10y, 10z, 10w) and a communication server (2a, 2b), and - wherein t samp corresponds to the inverse of the sampling rate, and - the receiving party computer receives additional data packets (A1,... An, B1,... Bn) transmitted to it by the communications servers (2a, 2b) and determines which of the further data packets (A1,... An; B1,... Bn) is each associated with the same additional time-stamp, and determines a speech data value (w) by selection or summation of the speech data values contained in the further data packets (A1,... An, B1,... Bn) each with the same timestamp (T'), and holds it available for the receiving party. - the sending party speech information is created and this speech information is divided by the respective sending party computer into individual, numerical speech data values (x), - data packets (X1,... Xn) from the sending party, each comprise at least one numeric speech data value (x), each of which is associated with at least a timestamp in the form of a consecutive number which determines the sequence of the individual speech data values (x) with respect to the speech data values of the other data packets - the data packets (X1,...

An, B1,... Bn) transmitted to it by the communications servers (2a, 2b) and determines which of the further data packets (A1,... An; B1,... Bn) is each associated with the same additional time-stamp, and determines a speech data value (w) by selection or summation of the speech data values contained in the further data packets (A1,... An, B1,... Bn) each with the same timestamp (T'), and holds it available for the receiving party.
