Like many cryptosystems, PGPfone[13] requires a method of reliably exchanging binary data over noisy phone lines. This paper describes a method of encoding binary data into a \radio alphabet," using a feature-based distance metric to measure phonetic confusibility, then using this metric in a GA to select appropriate words from a larger list of candidate words. This work indicates several larger issues that should be addressed in any (human) language engineering project.
