Abstract :
A NMOS vocoder IC, compatible with the LPC-10-2400-b/s speech coding standard, is described. The IC implements an adaptive linear predictive coding (LPC) spectral analyzer, a pitch decoder using Gold´s algorithm, and a speech synthesizer. The algorithms, architecture, and circuit design methods have been clearly optimized to allow a single-chip implementation.
