Production V-1 COARTICULATION IN CONTRASTIVE RUSSIAN STOP SEQUENCES
Lisa Davidson, New York University
Paper File Additional Files
  The articulation of stop-stop #CC, C#C, and #CəC by native Russian speakers is examined using ultrasound imaging. Three main issues are addressed: whether syllable structure affects coordination of consonant sequences, whether coarticulatory resistance interacts with syllable structure, and whether second language learners could transfer their ability to produce C#C sequences to #CC sequences. The tongue shape trajectories suggest that C#C and #CC coarticulation and timing are not interchangeable, and that syllable structure does interact with coarticulatory resistance. In some cases, native Russian #CC articulation is more similar to #CəC than to C#C, suggesting that learning the timing and coarticulation of these sequences may be a challenge for L2 acquisition.
Production V-2 Effects of Syllable Structures on V-to-V Coarticulation (Thai vs English)
Pik Ki Peggy Mok, Department of Linguistics and Modern Languages, The Chinese University of Hong Kong
Paper File
  This paper investigates the effects of syllable structures on v-to-v coarticulation. It was hypothesized that open syllables (V#CV) would allow less v-to-v coarticulation than closed syllables (VC#V). Languages with simple syllable structure (Thai) would allow less v-to-v coarticulation than languages with complex syllable structure (English). /C1V1#C2V2/ and /C1V1C2#V2t/ sequences were recorded from six native speakers in Thai and English. F1 and F2 frequencies were measured. Results show that English consistently allows more v-to-v coarticulation than Thai, but open and closed syllables do not affect v-to-v coarticulation differently. The results on open and closed syllables are compatible with ÷hmanís model of coarticulation.
Production V-3 Stroboscopic-cine MRI and acoustic data on gradual tongue movements in Korean palatalization: implications for its coarticulatory effect
Hyunsoon Kim, Hongik University, Seoul Korea
Paper File
  The present study addresses the question of whether the tongue rises as high as in the vowel /i/ in two types of Korean palatalization: a) when consonants take place before /i/ within a morpheme and b) when the consonants /t, th/ occur before /i/ across a morpheme boundary, changing into their affricate counterparts. For this purpose, we looked into stroboscopic-cine magnetic resonance imaging (MRI) data on tongue movements taken from two native speakers of the Seoul dialect. The MRI results that the tongue gradually rises and moves front throughout the target consonants are further confirmed by our acoustic data taken from ten Seoulites including the subjects in the MRI experiment. From this, we propose that Korean palatalization is a phonetic coarticulatory effect in the sense of ÷hman (1966) and Keating (1985, 1988).
