ABSTRACT:
A voice analyzing apparatus comprises: a first analyzer that analyzes a voice into harmonic components and inharmonic components: a second analyzer that analyzes a magnitude spectrum envelope of the harmonic components into a magnitude spectrum envelope of a vocal cord vibration waveform, resonances and a spectrum envelope of a difference of the magnitude spectrum envelope of the harmonic components from a sum of the magnitude spectrum envelope of the vocal cord vibration waveform and the resonances; and a memory that stores the inharmonic components, the magnitude spectrum envelope of the vocal cord vibration waveform, resonances and the spectrum envelope of the difference.
