We have developed proprietary method of the speech coding, which have named as Sinusoidal Pulsed Representation (SPR). This method differs from well-known first of all by more complex model of speech synthesis. Speech is synthesized as mixture of three components:
- harmonics of the fundamental frequency (Pitch),
- noise,
- aperiodic pulses
Such representation allows to synthesize all speech sounds, including voiced, unvoiced, mixed and also complex transients with aperiodic vibration of vocal cords.
