TL;DR: In this article, a speech coder and decoder methodology was proposed to represent pitch excitation and codebook excitation source energies by parameters that are readily transmissible with minimal transmission capacity requirements.
Abstract: A speech coder and decoder methodology wherein pitch excitation and codebook excitation source energies (100) are represented by parameters that are readily transmissible with minimal transmission capacity requirements. The parameters are the long term energy value, a short term correction factor which is applied to the long term energy value to match the short term energy, and proportionality factor(s) that specify the relative energy contribution of the excitation sources to the short term energy value (101).
