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.

15. A disordered voice processing apparatus comprising:
-
an input unit configured to input a nasal sound signal and an oral sound signal including a separation means for separating the oral sound signal and the nasal sound signal from each other; a memory configured to store the nasal sound signal and the oral sound signal; and a processor configured to generate a restored voice signal from the nasal sound signal and the oral sound signal, wherein the processor is configured; to recognize the nasal sound signal and the oral sound signal on a basis of a phoneme; classify 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; to extract multiple voice components from each of the nasal sound signal and the oral sound signal; to acquire 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 to synthesize a restored nasal sound signal and a restored oral sound signal based on at least the restored voice components to generate the restored voice signal. - View Dependent Claims (16, 17)
