<p>A technique for high quality low bit rate speech coding is described. The technique involves developing a new pulse location and amplitude sequentially based on the pulse location and amplitude previously obtained concerning a speech signal on a frame basis. As a first step a pulse close to the location of the new pulse based on the pulses previously obtained is selected. Next, the new pulse is developed based on the selected pulse. At least the new pulse is then coded. The invention greatly reduces the amount of calculation required compared with prior techniques.</p> |
