Abstract :
The root LPC system has closed form analysis and formant like synthesis structure. By using quadratic coefficient quantization and section repeat its data rate can be lower than 1Kbps. By including representative residual signal of variable repetition rate its quality can be continuously improved. A special purpose NMOS-LSI chip was built to implement the synthesis function.
