Computer Program to Convert Word Orthography to Phoneme Equivalents. Final Report.
Leton, Donald A.
A computer program to convert the orthography of English words to phoneme equivalents was developed. For purposes of this study, a grapheme was defined as the minimum unit of orthography to which a segmental phoneme, a unitary phoneme combination, or a nonphoneme would be associated. An informational processing model for automatic reading was then constructed. A conditional association matrix, with 65 rows for grapheme signals and 45 columns for phoneme designates, was hypothesized as an adequate structure to accommodate all of the English grapheme-phoneme associations. Two phases of the association matrix were described: a dynamic learning phase and a skilled state or processing phase. The acquisition of reading skills was simulated by attempting to write a computer program for each grade level in a basic reading series. Programs were written for the preprimer and primer of the Lippincott series. These programs achieved 96 percent accuracy in processing the 190 words in the preprimer and 85 percent accuracy in processing the 770 words in the primer. The types of errors are discussed. The associations and rules for processing the grade-1 readers in the series have also been written. The results of the research demonstrate the feasibility of automated reading. References and an appendix of data are included. (Author/WB)
