    Abstract: Disclosed is a function of applying a speech signal to a harmonic codec without distinguishing a voiced signal from an unvoiced signal. A peak portion having harmonic and non-harmonic components is extracted from a speech signal based on morphology, and a characteristic frequency is extracted from the extracted peak portion and applied to a harmonic codec. The harmonic codec is a general sinusoidal codec applied to all speech signals. Accordingly, a morphology-based pre-processing method for extracting a characteristic frequency can be easily applied to other speech signal characteristic extracting methods, and performance of other systems using the morphology-based pre-processing method is significantly increased due to a characteristic of a pre-processed signal.
