Abstract
The Adaptive Density Pulse (ADP) is a new efficient excitation model for low bit-rate speech coding. This ADP is a pulse train whose density (spacing interval) is constant within a subframe but can be varied subframe by subframe. The ADP excitation signal is defined and a procedure for finding the optimal ADP excitation is presented. Some results on investigating the effects of the ADP parameters on the synthesized speech quality are discussed.
