We present new waveform-interpolation coding procedures which allow perfect reconstruction of the speech signal from the unquantized parameter set. Instead of using adaptive parameter extraction methods, we combine a time warping of the original signal with nonadaptive parameter extraction methods. The new coding structure has good performance at low bit rates and provides convergence to the original waveform with increasing rate.
