This study sought to analyze phoneme/grapheme correspondences in a 17,310-entry word list drawn from the Thorndike-Lorge word list and Merriam-Webster's New Collegiate Dictionary. Phase one of the research, which has also been reported separately, also sought to determine how closely American-English orthography approximates the alphabetic principle. Correspondences were analyzed irrespective of context, in relation to syllable position, and in relation to position in stressed and unstressed syllables. Phase two sought to develop an algorithm to spell on a phonological basis and to analyze errors. Extensive appendixes to the report list the words in the corpus, tabulate phoneme occurrences, detail the algorithm, and list words spelled correctly by the algorithm and errors. (AA)
