Abstract

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.
