This paper describes the application of the Pulsed Residual Excited Linear Prediction (PRELP), a variation of the well known CELP algorithm to coding 7kHz wideband speech. The coder is to be used in the audio description of television. The PRELP algorithm operates at the source rate of 14.1 kb/s and uses an innovative excitation which is adapted for wideband speech. In addition to producing high quality speech, the algorithm simplifies the complexity of the encoder/decoder. This ensures that a cost effective hardware implementation can be achieved. The coder also employs a novel codebook gain quantiser, which is adaptive to the energy of the LPC synthesis filter response.
