A relatively new area of research in centering on the phonetic encoding of information. This paper deals with the possible computer applications of the Sound Approach ^© English phonetic alphabet. The authors review some preliminary research into a few of the more promising approaches to the application of the processes of machine learning to this phonetic alphabet for computer spell-checking, computer speech recognition etc. Applying mathematical approaches to the development of a data-based phonetic spelling recognizer, and speech recognition technology used for language pronunciation training in which the speech recognizer allows a large margin of pronunciation accuracy, the authors delineate the parameters of the current research, and point the direction of both the continuation of the current project and future studies.
