Abstract
In this work, we carried out a research on speech recognition system particularly recognition system of Arabic words based on wavelet network. Our approach of speech recognition is divided into three parts: parameterization phase, training phase and recognition phase. This paper aims at introducing an intelligent algorithm of training of wavelet network for words recognition system. It presents also experimental results and a comparison between old training algorithm based on randomly training of wavelet network and our new approach based on intelligent algorithm of training of wavelet network for recognition system of Arabic words.
