Abstract

Hangul(Korean alphabet) cannot know the correct pronunciation of strings as well as words only by orthography. To solve the difficulty, it is necessary to develop the I/O unit to input Hangul and perfectly output a pronunciation method. ‘The basic change table’ has been recently made to develop the I/O unit of Hangul pronunciation that a pronunciation method is automatically outputted immediately after Hangul is inputted. The phonetic change of two letters inputted is considered as the change of 28 final sounds and 19 initial sounds. In ‘the basic change table’, 532(28*19) pairs of (final sound, initial sound) are converted into another pairs of (final sound, initial sound). Using this table, automatic phonetic conversion succeeded in a computer experiment and the basis of realizing the making of I/O unit was built up. However, there is considerable irregularity where the pronunciation method by the basic change table is different from real pronunciation. It resulted in the need of this study. The purpose of this study is to present solution for strings that the result of phonetic conversion based on the basic change table does not agree with the pronunciation by the regulation of standard Korean pronunciation and to develop perfect I/O unit of Hangul pronunciation. Recently, vowel-related pronunciation irregularity has been perfectly solved for the Clause 15 and 29 of the regulation of standard Korean pronunciation. However, a problem of the correct I/O method for glottalization that has much more changes remains to be solved. Because one pair of (final sound, initial sound) is arranged only for another pair of (final sound, initial sound) in phonetic changes by the basic change table, glottalization associated with the Clause 24, 26, 27, and 28 of the regulation of standard Korean pronunciation has many changes. This study described solutions for the Clause 24 of the regulation of standard Korean pronunciation for the glottalization of verb stems, the Clause 26 of the regulation of standard Korean pronunciation for Sino-Korean words, and the Clause 27 of the regulation of standard Korean pronunciation for pre-nounal components to help the I/O unit. Furthermore, for the solution of glottalization of the Clause 28 of the regulation of standard Korean pronunciation that should have -ㅅ(s)-(saisiot) of a pre-nounal function that is considered as the highest difficulty, the types of compounds with a pre-nounal function were divided into three. As a result, the number of compounds to be registered became minimized, memory capacity was reduced, and an output error of pronunciation method was minimized.
