To encode the speech quality with reduce the redundancy within samples that resulted from domain processing method like PCM and LPC, Source coding or Waveform coding methods can be considered. However, it is well known that when conventional sampling methods are applied directly to speech signal, the required amount of data is comparable to or more than that of uniform sampling method. To overcome this problem, a new hybrid methods is proposed, in which hybrid domain coding is applied to two low-pass filters in lower bandwidth and the remain signals are compensated by the Gaussian white signal and harmonics, which is used to get high quality speech in higher bandwidth.
