Abstract
A very small, very flexible, high-quality, linear predictive vocoder has been implemented with commercially available integrated circuits. This fully digital realization is based on a distributed signal processing architecture employing three commercial Signal Processing Interface (SPI) single chip microcomputers. One SPI implements a linear predictive speech analyzer, a second implements a pitch analyzer while the third implements the excitation generator and synthesizer.
