What I need to do is:
-Perform the decomposition of voiced sounds of speech signal into harmonic components. -Re-synthesized signal by using the harmonic components. -Perform scrambling and reverse synthesis unvoiced sounds of the speech signal based on LPC. -Implement this synthesis for non-stationary signal, based on harmonic model the only modeling voiced speech segments. Detection of voicing do based on energy detection and ZCR.

Dan Ellis' code available at this link might get you started on sinusoidal analysis/resynthisis: https://labrosa.ee.columbia.edu/matlab/sinemodel/
