Echo canceller using short time spectral analysis

The invention relates to an arrangement (1) for communication with a subscriber (4). It is proposed in the arrangement (1)Spectral analysis means (7) for generating short-term spectral values ​​(Y (i)) of received signals (E) which are participant voice signals temporarily superimposed by echoes of transmission signals (S) transmitted by the subscriber (4),Echo canceling means (8) for estimating short-term spectral values ​​of the echoes (Xw(i)) and for forming difference values ​​(D (i)) between the short-term spectral values ​​(Y (i)) of the received signals (E) and the estimated short-term spectral values ​​(Xw(i)) the echoes andSpeech recognition means (13) for evaluating the difference values ​​(D (i)) provided.
