Abstract :
This paper describes the proprietary implementation of a real-time software based HY-2 compatible channel vocoder algorithm. The HY-2 algorithm was used prior to linear predictive coding (LPC) vocoders for low bit rate voice communications at 2400 bps. This implementation is a unique and instructive implementation of a parametric vocoder, producing high quality speech
