  PHD in Signal processing and Speech Processing . Thesis Title : " AM-FM analysis of Speech and Empirical Mode Decomposition "Thesis Abstract : The thesis investigates and endorses a non-linear and non-stationary data analysis technique, called Empirical Mode Decomposition (EMD), as an alternative to the conventional methods of speech analysis. The thesis commences with a study of EMD as an adaptive AM-FM analysis technique, its characteristics, and its advanced variants used to curtail mode-mixing - an inherent but undesirable phenomenon specific to EMD. Based on this study, this thesis first proposes a modified EMD algorithm, which curtails mode-mixing, but at a much faster rate than the existing advanced noise-assisted variants of EMD. Secondly, the thesis investigates the ability of EMD, and its variants, in extracting the latent characteristics of the speech signal, for different speech sounds with varying waveform characteristics. The thesis, then, showcases the utility of EMD and its variants in two different speech processing applications. In the first application, the thesis proposes a principle or framework to detect the Glottal Closure Instants (GCIs), of the speech signal, from its Intrinsic Mode Functions (IMFs) derived from EMD and its variants. The objective here is to provide an alternative to the state-of-the-art methods based on short-time Linear Prediction (LP) analysis, which is based on the source-filter theory. In the second application, this thesis investigates the capability of the IMFs of the speech signal, in capturing speaker specific information, which can complement the Mel filterbank. Show less
