Abstract

Abstract The invention relates to a method for converting channel vocoder parameters into LPC vocoder parameters, the LPC vocoder parameters being calculated from the smoothed power spectrum of the channel vocoder parameters by an inverse discrete Fourier transformation. According to the invention, for a prescribed channel number of the channel vocoder and a prescribed parameter number of the LPC vocoder, matrix elements are calculated from the variables, which are constant in this case, and the LPC vocoder parameters are computed from the channel vocoder parameters by matrix multiplications. <IMAGE>
