Abstract
The viability of a low-cost real-time narrow-band voice coder with good speech quality will be demonstrated. We describe a hardware implementation of the U.S. Government Enhanced Linear Predictive Coder (LPC-10e), which compresses speech sampled at 8 kHz to 2400 bits per second. The hardware employs two fixed-point digital signal processors operating at 8 MHz and consumes 2.5 W.
