Production and perception of second language sounds are typically influenced by second language learners' native language sounds. In this study we investigate how the Korean language influences Korean speakers' production of English alphabets. In the experiment conducted to prepare for this study 16 native speakers of Korean pronounced English alphabets. Then three native speakers of English evaluated the Korean subjects' pronunciation of them. The results show that the Korean subjects' native language (i.e., Korean) influences their production of the English alphabets. When Korean has sounds corresponding to English alphabets, the English subjects rate the Korean subjects' production of them good. For instance, Korean has voiceless stop phonemes, hence their production of English alphabets was rated good by the English subjects. The Korean subjects' production of English alphabets containing the sounds that do not exist in Korean was rated poor by the English subjects. For instance, Korean does not have voiced fricative phonemes, hence their production of English alphabets was rated poor.

In the present study, the production of grammatical morphemes of Korean-speaking children with and without developmental language impairments was investigated. Ten children with language impairments (LI) (CA: 4; 4-6; 11, LA: 3; .6-5; 10) and 10 normal children (CA: 3;1-6;3, LA: 3;5-5;11) with matched language abilities participated in the study. Sixty pairs of pictures were used to elicit 12 types of predetermined grammatical morphemes. The two pictures of a pair were designed to elicit two sentences of the same sentence structure. After the investigator described one picture of a pair, the children were asked to describe the other picture. The LI children made more errors than the normal children in the production of 6 types of grammatical morphemes including: locative case marker, dative case marker, two connective endings of predicates representing cause and goal, and suffixes for passive and causative verbs. However, the LI children produced some grammatical morphemes as accurately as. the normal children. The two groups were similar in their error patterns. Some explanations for Korean-speaking LI children's use of grammatical morphemes were suggested.

The current study investigated whether Korean learners' English-learning environments, especially target English accent (General American English (GAE) vs. Southern British English (SBE)) and English-language experience affected their production of English vowels. Thirty six EFL learners, 27 ESL-US learners, and 33 ESL-UK learners produced 8 English vowels with a bVt frame (beat, bit, bet, bat, bought, bot, boat, boot). The learners' productions were acoustically analyzed in terms of F1 and F2 frequencies. The overall results revealed that the learners' target accent had an effect on their production of some English vowels. The EFL and ESL-US learners' (especially, female learners') production of bought, bot, boat, and boot, which show characteristic differences between the GAE and SBE accents, was closer to that of the native American English (AE) speakers than the native British English (BE) speakers. In contrast, the ESL-UK learners' production of bought and bot demonstrated the opposite pattern. Thus, the impact of target accent was not demonstrated across the board. The effect of the learners' different English-language experience was also rather limited. This was because the EFL learners' production was not much different from the ESL-US learners' production, in spite of the ESL-US learners' residence in the US for more than 9 years. Furthermore, the Korean learners, irrespective of their different English-language experience, tended to produce bit and bat with lower F1 than the native AE and BE speakers, thus resulting in bit and bat to be produced similarly to beat and bet, respectively. This demonstrates the learners' persistent L1 effects on their English vowel production despite the learners' residence in the English speaking countries or their high English proficiency.

Language transfer means that the speaker's first language or previously acquired language influences on the production of the target language. This study aims at examining if there is native language influence on the production of English intonation by Korean speakers. The pitch accent patterns and the values of duration, F0, and intensity of the stressed vowel of the word with emphatic accent in the sentence produced by Korean speakers are compared to those of American English speakers. The results show that when the word receives emphatic accent in the sentence, American English speakers put H* accent on the stressed syllable of the word, but Korean speakers mostly assign high pitch on the last syllable of the word and have LH tonal pattern despite the fact that primary stress does not come on the last syllable within a word. In addition, comparison of the values of duration, F0, and intensity of the stressed vowel of the word with emphatic accent to those of the word with unmarked neutral accent shows that Korean speakers do not realize the intonation of the accented word appropriately because the values decrease even though the word has emphatic accent. This study finds out that there are differences in the production of English intonation of the word with emphatic accent between native speakers of English and Korean speakers, and that there is negative transfer of Korean intonation pattern to the production of English intonation by Korean speakers.

Traditionally it has been assumed that written abilities are completely dependent on phonology. Therefore spoken and written language skills in aphasic patients have been known to exhibit similar types of impairment. However, a number of latest studies have reported the findings that support the orthographic autonomy hypothesis. The purpose of this study was to examine whether fluent aphasic patients have discrepancy between speaking and writing skills, thereby identifying whether the two skills are realized through independent processes. To this end, this study compared the K-FAST speaking and writing tasks of 30 aphasia patients. In addition, 16 aphasia patients, who were capable of producing sentences not only in speaking but also in writing, were compared in their performances at each phase of the sentence production process. As a result, the subjects exhibited different performances between speaking and writing, along with statistically significant differences between the two language skills at positional and phonological encoding phases of the sentence production process. Therefore, the study's results suggest that written language is more likely to be produced via independent routes without the mediation of the process of spoken language production, beginning from a certain phase of the sentence production process.

The purpose of this study is to investigate the comprehension and production of various tense markings in Korean-speaking children with and without language delay. Thirty children with language delay(LD) and 30 typically developing(TD) children participated in the study. In each group, half were at the age of 4-years and the other half at 7-years. In both the comprehension and production task, 28 verbs containing four types of tense markings were used: past tense '-et ta', two present progressives '-ko itta', '-enta', and future tense '-elyeko hanta'. In the comprehension task, the children were presented with three printed still-scenes of video recording of a verb action, each representing future, present progressive, and past tense of the verb, respectively. Then they listened to the action verb with one of the 4 tense markings and had to pick the scene that matched the verb tense. In the production task, the children were given one of the three scenes and asked to produce the verb with appropriate tense marking. In both tasks, the LD children performed significantly worse than the TD children, and the older children performed significantly better than the younger children. Interestingly, the pattern of performances across different types of tense markings at the two language-age levels were closely similar in LD children and TD children. This similarity of groups seemed stronger in the comprehension task than the production task.

This study investigates the effect of Japanese (L1) on the production of the Korean rhythmic structure. Korean and Japanese have typologically different rhythmic structure as a syllable-timed language and mora-timed language, respectively. This rhythmic difference comes from the different phonological properties of the two languages. Due to this difference, Japanese speakers that are learning Korean may produce a different rhythm than native Korean speakers' rhythm. To investigate the influence of the native language's rhythm on the target language, we conducted an acoustic analysis using acoustic metrics such as %V, VarcoV, and VarcoS. Four Korean native speakers and ten advanced Japanese Korean learners participated in a production test. The analyzed material consisted of six Korean sentences that contained various syllable structures. The results showed that KS and JS's rhythms are different in %V as well as in VarcoV. In the case of VarcoS, significant rhythmic difference was observed in the VC and CVC syllable, in which the coda segment is nasal sound. This study allowed us to observe the influence of L1 on production of L2 rhythm.

The primary goal of this study is to find out how the effect of speaking rate has some influence on the production and perception across languages. Through both experiments of production and perception, an English native speaker changes both production and perception simultaneously. Especially the production of the temporal features changes relatively fast. On the contrary, Chinese and Korean speakers changes their production rather than perception by following the speaking rate.

It is well known that Japanese prosodic structure assumes mora below the syllable tier. Syllables with V or CV structure are counted as having one morn whereas those with coda consonants /-pp, -tt, -kk, -ss, -N/ or long vowels are counted as having two morns in Japanese. This study measured the acoustic duration of these special moras ('tokusyuhaku') produced by Tokyo dialect speakers to see if they are isochronic with V or CV. It also examined the production of Korean(Seoul/Kyungsang dialect) and Chinese native speakers loaming Japanese as a second language to examine how the learners' first language influence their second language. Finally, it examined how speakers of the Akita dialect, which is blown as a syllabeme dialect in Japanese, produced them. The results showed that intra-speaker variation as well as inter-speaker variation was observed in the production by Akita dialect speakers. Production of native speakers of Chinese and Kyungsang dialect of Korean -- which have vowel length contrast in their phonological systems -- showed a similar result to Tokyo dialect speakers, which implies the influence of the learners' first language on the acquisition of the second language.
