Phonetic encoding of coda voicing contrast and its interaction with information structure in L1 and L2 speech
نویسندگان
چکیده
This study examines the coda voicing effect in English on production of preceding vowel by comparing L1 and L2 speech. Particular attention is paid to how coda voicing contrast is encoded in temporal vs. spectral dimensions, how the effect interacts with information structure (with varying focus types), and how the use of information structure differs in L1 vs. L2. Both English (native) and Korean (non-native) speakers show a comparable pattern in the temporal dimension (vowel duration), but Korean speakers fail to encode the spectral attribute (vowel F1/F2) due to coda voicing. Furthermore, while native speakers make use of information structure in an efficient way that is accountable by the output-oriented and the system-oriented constraints, non-native speakers do not use information structure as efficiently. Alongside the L1/L2 issues, a ‘long-distance’ coda voicing effect is observed on VOT of the preceding initial stop, which illuminates the nature of the coda voicing effect.

Phonetic Encoding of Coda Voicing Contrast under Different Focus Conditions in L1 vs. L2 English
This study investigated how coda voicing contrast in English would be phonetically encoded in the temporal vs. spectral dimension of the preceding vowel (in vowel duration vs. F1/F2) by Korean L2 speakers of English, and how their L2 phonetic encoding pattern would be compared to that of native English speakers. Crucially, these questions were explored by taking into account the phonetics-proso...
متن کاملDissociable Levels of Speech Processing in Second Language Perception
It is generally accepted that there are at least two levels of speech processing: a level that processes categorical (and possibly indexical) acoustic information, and a level that processes abstract information for phonemic/lexical contrasts. However, little is known about how these levels may interact to impede or facilitate the perception of non-native speech contrasts. Our study evaluates w...
متن کاملSyllable Structure Universals and Native Language Interference in Second Language Perception and Production: Positional Asymmetry and Perceptual Links to Accentedness
The present study investigated how syllable structure differences between the first Language (L1) and the second language (L2) affect L2 consonant perception and production at syllable-initial and syllable-final positions. The participants were Mandarin-speaking college students who studied English as a second language. Monosyllabic English words were used in the perception test. Production was...
متن کاملCategorical patterns, phonetic integration and within-category variability in the recognition of spoken words in a second language
It has been shown on several occasions that speech perception in a second language (L2) is often tainted by the phonetic and phonological structures of a listener’s native language (L1). As languages vary in their phonological inventories, listeners often have to develop new phonological categories during acquisition in order to recognize words and phonemes in their L2. Recent evidence on the p...
متن کاملSpeech Workshop: New Perspectives on Developmental Models
In this model, speech perception by adults is characterized as an active, information-seeking process whereby native listeners detect the most reliable acoustic parameters that specify phonetic segments and sequences, using highly over-learned, automatic selective perception routines. In laboratory perceptual tasks, differentiation of native L1 phonetic contrasts is rapid and robust in suboptim...
