ABSTRACT:
The invention describes one way of coding a speech signal without the elaborate searhing of a stochastic codebook. An "ideal" Regular Pulse Excitation (RPE) is used as the starting point for the method. The five strongest RPE pulses are quantized with equal amplitude and differ by their sign. The other RPE pulses are set to zero. This method, which is simple and can be carried out quickly, provides the same speech quality as with considerably more elaborate closed-loop methods.
