The Role of Phonetic Processing in Second Language Acquisition
Susan G,Guion,Borim Lee 한국영어학학회 2006 영어학연구 Vol.- No.21
Experience with a first language shapes the processing of phonetic input. Acoustic information that is used to cue phonological distinctions in the first language is weighted more heavily. Correspondingly, acoustic information not used to cue phonological distinctions comes to be systematically under-attended. In the domain of perception, Guion and Pederson (in press) investigated the plasticity of the attentional system with regard to processing novel acoustic cues. The acoustic information used by native speakers of a tone language, na?ve speakers of non-tone languages, and adult learners of a tone language was investigated. The adult learners were found to have retuned their phonetic processing to attend to acoustic cues employed by tone languages. In the domain of production, Lee, Guion, and Harada (in press) investigated the relationship between acoustic cues used in first language prosody and the production of English unstressed reduced vowels. Korean-English and Japanese-English bilinguals who began learning English before the age of 6 or after the age of 15 were studied. The early bilingual groups were nearly native-like but showed some characteristics that could be attributed to first language processing. The late bilinguals were less native-like but, nonetheless, exhibited productions closer to native-like norms than would be predicted by the transfer of the first language phonological system alone. These results indicate that early learners can learn to attend to acoustic cues not used in the phonology of their first language and, thus, develop productions that come close to native norms. Late learners, on the other hand, show evidence of perceptual plasticity, but are less likely to attain native-like production norms than early learners.

Borim Lee(이보림),Susan G. Guion 한국음운론학회 2008 음성·음운·형태론 연구 Vol.14 No.2
This study investigated hyperarticulated, clear speech production of English stress by second language speakers of English. The results of the experiment revealed that second language learners can, to some extent, control their production and that they may have targets for stress production that are undershot but may be reached with more articulatory effort. This suggests that learners regulate phonetic variation in their second language in much the same way as they do for a first language and that when they devote enough attentional resources, they may approximate more native-like productions of specific acoustic features. Three of the acoustic correlates of English stress investigated, i.e., pitch, intensity and duration, were enhanced in clear speech with the exception of duration for Japanese bilinguals. However, vowel reduction in unstressed vowels did not change in clear speech, indicating that it may not be present in learners’ target representations.

Effects of Experience on the Production of English Unstressed Vowels
이보림,Lee, Bo-Rim,Guion Susan G. The Korean Society Of Phonetic Sciences And Speech 2006 말소리 Vol.60 No.-
This study examined the effect of English-language experience on Korean- and Japanese-English late learners' production of English unstressed vowels in terms of four acoustic phonetic features: F0, duration, intensity and vowel reduction. The learners manifested some improvement with experience. The native-like attainment of a phonetic feature, however, was related to the phonological status of that feature in the speakers' native language. The results suggest that the extent to which the non-native speakers' production of English unstressed vowels improved with English-language experience varied as a function of their native language background.
