In this paper a novel DCT prototype interpolation synthesis process is presented and used to model the input speech signal. The compression efficiency of the DCT when applied to prototype pitch segments, leads to 1.7/2.4 kb/s DCT-PIC systems which can deliver decoded speech of high communication quality.
