Claim:
1. A disordered voice processing method comprising: receiving a nasal sound signal and an oral sound signal, and the nasal sound signal and the oral sound signal are acquired from an input unit with a separation means for separating the oral sound signal and the nasal sound signal from each other; recognizing the nasal sound signal and the oral sound signal by phoneme; classifying each of the recognized nasal sound signal and oral sound signal into a normal voice signal and a disordered voice signal using a phoneme characteristic table, wherein the phoneme characteristic table includes information of nasal sound and oral sound of normal voice separately; extracting multiple voice components from each of the nasal sound signal and the oral sound signal; acquiring restored voice components by processing at least a portion of disordered voice components of the multiple voice components on a basis of a phoneme, wherein the restored voice components are acquired for each of the nasal sound signal and the oral sound signal using the phoneme characteristic table; and synthesizing a restored nasal sound signal and a restored oral sound signal based on at least the restored voice components to generate a restored voice signal.
