Abstract :
In this paper, a novel technique for speech signal reconstruction is described using Empirical Mode Decomposition (EMD) of speech signal. EMD is applied for finding the glottal source signal of speech signals. After getting the source information, vocal tract filter response is determined and the original speech signal is reconstructed. The experimental result derived establishes the effectiveness of the proposed method.
