Abstract: in this paper we present a system for speech recognition using neural network from obtained data of power spectral density peaks. For this work, a small size vocabulary containing the word "yes " and "no " is chosen. Spectrum features is extracted from estimated power spectrum by Autoregressive parametric method in each frame of speech signal. And it is given to feed forward Back propagation neural network with gradient descent with adaptive learning rate training algorithm. Network is trained for classification to two classes.
