A method for speech detection in a telecommunication system comprising a signal source and a signal processor for processing a signal to be observed. In the method desired identification numbers are determined (107-110) from said signal, said identification numbers are fed into a neural network, output values are calculated (111) for speech and noise neurons on the basis of said identification numbers in said neural network and a decision is made (104) on whether said signal is speech or noise.
L'invention concerne un procédé de détection de la parole dans un système de télécommunications, comprenant une source de signaux et un processeur de signaux, permettant de traiter un signal destiné à être observé. Selon ce procédé, on détermine les numéros d'identification voulus (107-110) à partir dudit signal, ces numéros d'identification étant introduits dans un réseau neuronal. On calcule ensuite les valeurs de sortie (111) des neurones de la parole et du bruit, sur la base desdits numéros d'identification du réseau neuronal, puis on décide (104) si ledit signal correspond à la parole ou au bruit.
