Abstract

Empirical mode decomposition (EMD) algorithm is proposed as an alternative to decompose the magnitude spectrum of the speech signal into harmonic and spectral envelope components. The EMD is a tool for the analysis of multi-components signals. The analysis method does not require a priori fixed basis function like conventional analysis methods (e.g. Fourier transform and wavelet transform). The EMD algorithm decomposes adaptively a given signal into oscillation modes namely the intrinsic mode functions (IMFs) extracted from the signal itself. An adaptive method is developed to select the IMF index that enables to separate the harmonic component and the spectral envelope and then the IMF variance is used as a parameter to perform clustering in order to distinguish the IMFs that constitute the harmonic component and those constituting the spectral envelope. The proposed method is tested on both synthetic and natural speech signals.
