The design of an LPC speech synthesizer
Yongming Li, Hongyi Chen, Zheng Yu · 2002
A dedicated LPC speech synthesizer is presented in this paper. It mainly acts as a programmable 12-pole lattice filter with a 2-pole low-pass filter, a 12 bit D/A converter and a built-in interface to external CPU. The gate level logic simulation and the results of c programs shows that the synthesizer can synthesize high-quality speech at low data rate. It can be used in LPC analyze-synthesize systems and developments of LPC speech synthesizer IC.
