1. A method of generating linear prediction filter coefficient signals during frame erasure, the generated linear prediction coefficient signals for use by a linear prediction filter in synthesizing a speech signal, the method comprising the steps of: storing linear prediction coefficient signals in a memory, said linear prediction coefficient signals generated responsive to a speech signal corresponding to a non-erased frame; and responsive to a frame erasure, scaling one or more of said stored linear prediction coefficient signals by a scale factor, BEF raised to an exponent i, where 0.95.ltoreq.BEF.ltoreq.0.99 and where i indexes the stored linear prediction coefficient signals, the scaled linear prediction coefficient signals applied to the linear prediction filter for use in synthesizing the speech signal.
