“…Riney et al (2000) look at the English liquids /r/ and /l/ and discover that the substitution of flap /ɾ/ for English liquids is a distinguishing feature of interlanguage phonology constructed by Japanese speakers learning English as a foreign language. By studying Korean-accented English, Chung and Kim (2021) find that Korean-English speakers' English /l/ has significantly lower F2-F1 values than /l/ in Korean, but significantly higher F2-F1 values than /l/ produced by native English speakers. And the deviations in English liquids in Korean-accented English are negatively correlated to the degree of accents.…”

This paper provides an experimental study of interlanguage phonological characteristics of Chinese students learning Thai as a foreign language and the accentedness perceived by native Thai speakers. Both production and perception experiments were designed to see how Chinese students acoustically produced Thai final nasal consonants and how Thai native speakers perceived these Chinese-accented nasals. The production experiment compared the acoustic features of Thai final nasal consonants (i.e. /m/, /n/, and /ŋ/) produced by Chinese students and native Thai speakers (n = 5 in each group), who provided speech samples from a wordlist reading task, consisting of 28 words (840 tokens). Nasal acoustic properties of 840 tokens (duration, nasal murmurs, and formant transitions) were examined. The findings showed that the Chinese students produced significantly longer nasal duration and more drastic formant transitions compared to the native speakers. The perception experiment analyzed how native Thai raters (n = 10) rated speech samples concerning degrees of accentedness by using a 5-point Likert scale with 5 as the most native level. Based on this, the native Thai raters rated the Chinese students’ speech as 3.22 on average, while native Thai speech was judged with an average score of 4.65, which demonstrated that native Thai raters could distinguish foreign speech from those pronounced by native speakers. To find out to what extent nasal acoustic characteristics in Chinese students’ interlanguage phonology contributed to the degree of accentedness, stepwise regression analyses were utilized to discover that nasal duration was particularly important in accurately predicting accentedness in Thai with Chinese accents.

Purpose: The aim of this study was to examine acoustic characteristics of Korean–English (KE) bilingual children's productions of Korean and English /l/ sounds. Specifically, individual variability in KE bilingual children's productions of Korean and English /l/ was examined in relation to each child's initial age and duration of exposure to their first and second languages. Method: A total of five KE bilingual children, ranging in age between 5 and 8 years, were included in this study. Each KE child produced word-initial (WI) and -final (WF) English /l/ and WF Korean /l/ embedded in monosyllabic words, using a picture naming task. English /l/ productions of monolingual American English (AE)–speaking children were also included. Productions of AE children were from an existing large data set that includes English WI and WF /l/ productions. The AE group was included as a control group for the productions of English /l/ of the same dialect. First (F1) and second formant frequency (F2) values extracted at the /l/ midpoint and Euclidean distance (ED) between English WI and WF /l/ were analyzed and compared across the productions. Results: KE children produced Korean WF /l/ with significantly higher F2–F1 values than their English counterparts and AE children's WF /l/. Acoustic patterns of KE English WI /l/ were similar to those of AE WI /l/, but variations were seen by the initial age and duration of their exposure to English. Mean ED values between English WI and WF /l/ also differed by KE children's initial age and duration of exposure to English. Conclusions: These results showed that KE children produce Korean and English WF /l/ with acoustic distinctions, but their patterns vary by the initial age and duration of their exposure to English and Korean. These findings suggest that a more detailed language background should be considered when working with bi-/multilingual children to accurately assess and examine their articulation skills.
