Segmental prototype interpolation coding

Abstract

Current parametric speech coding schemes can achieve high communications quality speech at bit rates in the range of 2.4 to 1.5kbits/sec. Most schemes sample and quantise, at regular intervals, the “tracks in time” generated by the parameters of the speech production model. As a result, reconstructed “parameter tracks” do not evolve “smoothly” with time… (More)
