Abstract :
A new approach to restoring the intelligibility of divers´ speech uttered in a high-pressure atmosphere containing high percentages of helium gas is presented. The system processing architecture consists of a residually excited linear predictive coder (RELPC) with a novel implementation of time/frequency-domain relationships to simplify processing.
