Low-bit-rate speech coding with mixed-excitation and interpolated LPC coefficients

Jey-Hsin Yao, Yoshinori Tanaka

A very low-bit-rate speech codec combining mixed excitation technique and interpolation of LPC coefficients has been proposed. This coder is based on LPC vocoder structure and the target bit rate is 1.9 kb/s. Interframe coding techniques were used to achieve the low rate but at the same time, measures were taken to prevent error propagation. Informal listening tests showed that the proposed coder produces good quality speech.
