In this paper, reconstruction of speech signal is performed using a novel technique Empirical Mode Decomposition (EMD). EMD is mainly applicable for non-linear and non –stationary signals and therefore applicable for speech which is non linear and non-stationary. EMD is applied for finding the glottal source signal of speech which provide us the source information and then vocal tract filter is found out and original speech is reconstructed. Speech samples are collected from different Assamese dialect and the experimental result derived establishes the effectiveness of the proposed method.
