Abstract :
The authors describe a method for speech coding based on the prototype waveform interpolation (PWI) technique proposed by Kleijn (1991). A new, variable frame length form of this technique is proposed. The basic idea is consistent with that of the original PWI algorithm, but reduces its computational complexity. PWI methods have the potential for producing high quality speech at low bit rates
