The purpose of this study is to examine phonetically if the spelling errors produced by foreign Korean learners are related to learners’ pronunciation by analyzing the pronunciation of plain, tense, and aspiration sounds of foreign Korean learners using a Praat. A statistical analysis was performed on the listening, reading, and writing data produced by 18 foreign university students at the beginner level. The results are summarized as follows. First, foreign Korean learners accounted for the majority of errors in plain and aspiration sound among initial obstruent words. This can be interpreted as an extremely strong or very weak pronunciation of the word, because learners do not properly recognize the intensity of range in plain sounds. Second, the more accurate the learner’s perception was, the more accurate production can be made. Statistically, it was found that the production rate increased by 0.178 each time the perception rate increased by 1. Therefore, the correlation between perception and production is established. Third, the relationship between pronunciation and spelling is a relationship that increases by 0.652 each time the pronunciation increases by 1. It can be explained that there is a possibility that the learner may often write words as they pronounce them.

This research tried to figure out the realization effect of usage of anlauts /l/ and /n/ as nicely shown in North Korean news and to discuss the societal and lingual backgrounds from this investigation. Therefore, the research analyzed the tone of Chosun Central TV news’s announcer shown in TV news program from 2014 to 2017. With this analysis, the research tried to show the reason why there are differences in language policies regarding Korean consonant anlauts /l/ and /n/ between South Korea and North Korea and to discuss the realization effect of anlauts /l/ and /n/ after the implementation of the language policies. In chapter 2, the research considered policies for marking these consonants and gradual change for pronunciation rules and checked the reason why there is a difference In grammatical rules between North Korea and South Korea. According to previous research, exhibiting anlaut /l/ in North Korean pronunciation rules these days is not related to any historical evidence or regional dialect(Pyongyang dialect). In the environment that precedes /i/ and /j/ accepting the /n/ consonant was due to late palatalization relative to other regional dialects and also late elimination of the /n/ and therefore these objects are reflected into standard language policies in North Korea. In chapter 3, the research analyzed the realization effect of anlauts /l/ and /n/ in North Korean News. The percentage of the analut /l/ realizations was the anlaut /l/ was 83.78%, which means most of realizations were done by the anlaut /l/. Anlaut /l/ was followed by /j/, /a/, /o/, /ɛ/ and other vowels, and the percentage of anlaut /l/ used before most of the vowels was similar. For anlaut /n/ the situation that was followed by /j/ showed 21 times of the realization set and 24 times of the non-realization set, which resulted 46.6% and 53.4% respectively and illustrated similar aspects as shown in analut /l/. The realization phenomenon of anlaut /n/ occurred from the Middle Ages, and the research therefore confirmed that North Korea still uses the conservative pronunciation of the language.

Hong Mi-ju. 2014. A Study of phonological variation and Language Attitude of Word-initial tensification. The Sociolinguistic Journal of Korea 22(1). The purpose of this study is to contemplate the correlation between phonological variation and language attitude. It focuses specifically on explaining the phonological variation of word-initial tensification and Language attitude of variant [fortis]. Data have been collected from 30 informants who live in Daegu through interviews and questionnaires. This variable is examined and analysed to see how the variants are realized depending on the factors of informants' age and gender. The phonological variation based on the age and gender of word-initial tensification and language attitude of variant [fortis] are summarized as below: Fortis realization rate in word-initial does not have any significant value for age and gender. However, fortis phenomenon in word-initial is quite prevalent. Language attitude of variant [fortis] for age and gender does not have any significant difference. The greater number of speakers have positive attitude of variant [fortis]. The greater number of informants express willingness to support realization of variant [fortis] Several observation in few paragraphs have shown that if the speakers' s language attitude of a variant is positive, realization rate of a variant is more frequently. These result lead to the conclusion that there is correlation between phonological variation and language attitude of word-initial tensification.
