1. A method for linear predictive speech encoding comprising the steps of:

  • a) defining an error function that includes a constant value, the constant value comprising a chosen offset within a predetermined pitch interval;

    b) determining an optimal continuous vector;

    c) determining an error from the optimal continuous vector;

    d) determining if the error is less than a minimum error;

    e) providing optimal combination pitch-continuous coefficient values based upon in the minimum error; and

    f) providing a weighted vector quantization of an optimal continuous vector of continuous coefficient values.
