Does Orthography Affect L2 Tone Production and Perception? Donghui - PowerPoint PPT Presentation

Does Orthography Affect L2 Tone Production and Perception? Donghui Zuo, Qiuyue Chen, Peggy Mok Chinese University of Hong Kong

Introduction 2

Chinese Orthography • Chinese characters • Mandarin Pinyin • Major writing system • Official Romanisation for different Chinese system of Mandarin languages • Transparent (good • Opaque (no grapheme-to- consistent grapheme- phoneme to-phoneme correspondence) correspondence) • Tone is indicated by a • No information about number the tone • e.g., ‘horse’ ma 3 • e.g., ‘horse’ 馬 3

Cantonese & Mandarin • Shared orthography – Chinese characters • Different phonologies, tones for example: Tones Cantonese Mandarin T1 55 55 T2 25 35 T3 33 214 T4 21 51 T5 23 – T6 22 – 4

C-M tone correspondence Tsang-Cheung (1988) Cantonese Tone Mandarin Tone %Correspondence T1[55] T1[55] 93% T2[25] T3[214] 89% T3[33] T4[51] 91% T4[21] T2[35] 93% T5[23] T3[214] 76% T6[22] T4[51] 94% 5

Production Model (Chu, 2011) 6 Advanced learners

Research Question • Whether activations of the L1 phonological system • Facilitates/hinders Mandarin tone production? • Facilitates/hinders Mandarin tone perception? 7

Method 8

Subjects • 16 native speakers of Hong Kong Cantonese • 7 males, 9 females • 19-29 years old (mean = 23) • Students from the Chinese University of Hong Kong • Beginning learners of Mandarin (mean length of formal training = 2.6 years) 9

Materials - Production • Pinyin task • mi [mi] and na [na] with all four tones • 2 syllables × 4 tones = 8 tokens • Written in Mandarin pinyin • Chinese character task • ja [ja] and wu [wu] with all four tones (e.g., 壓 and 烏 ) • 2 syllables × 4 tones = 8 tokens • Written in Chinese characters 10

Materials - Perception • Pinyin task • Disyllabic minimal pairs (e.g. can1 guan1 參觀 ‘visit’ vs. can1 guan3 餐館 ‘restaurant’) • 1 sets × 6 pairs = 6 minimal pairs • Written in Mandarin pinyin • Read by a Mandarin native speaker • Chinese character task • Disyllabic minimal pairs (e.g., 字跡 zi4 ji4 ‘handwriting’ vs. 自己 zi4 ji3 ‘oneself’ ) • 2 sets × 6 pairs = 12 minimal pairs • Written in Chinese characters • Read by a Mandarin native speaker 11

Procedures - Production • Recording • All stimuli produced in isolation • 256 tokens collected • 128 Pinyin tokens (2 syllables × 4 tones × 16 speakers) • 128 Chinese character tokens (2 syllables × 4 tones × 16 speakers) 12

Procedures - Production • Transcription • Transcriber: 3 native speakers of Mandarin • Agreed transcription of at least two transcribers accepted as the actual tone produced No. of tokens Percentage 3 transcribers agree 173 67.6% 2 transcribers agree 80 31.3% No agreement 3 1% 13

Procedures - Perception • Pinyin task • Write down the tones of the second syllables • Both words of each pair presented once • 192 responses (6 pairs × 2 words × 16 subjects) • Chinese character task • Two-alternative forced choice task • Both words of each pair presented once • 384 responses (12 pairs × 2 words × 16 subjects) 14

Results 15

Production • Pinyin task • %Err = 2.3% (only 3 errors out of 128 tokens) • Character task • %Err = 43.4% • t(15) = -7.678, p < 0.001 16

Production (cont.) • Confusing T1 with T4, T2 with T3 45 40 35 30 %Err 25 pinyin 20 character 15 10 5 0 T1-T2 T1-T3 T1-T4 T2-T3 T2-T4 T3-T4 Confusable pairs 17

Perception • Pinyin task • %Err = 47.9% • Chinese character task • %Err = 11.7% • t(15) = 5.495, p < 0.001 18

Perception (cont.) • Confusing T1 with T4, T2 with T3 45 40 35 30 %Err 25 pinyin 20 character 15 10 5 0 T1-T2 T1-T3 T1-T4 T2-T3 T2-T4 T3-T4 Confusable pairs 19

Discussion 20

Error Patterns • T2-T3 pair • Also found in learners of other language background • Possible accounts: • Acoustic similarity (Kiriloff, 1969) • Perceptual assimilation (Best, 1995) • T3 Sandhi 21

Error Patterns (cont.) • T1-T4 pair • Not found in learners with some other backgrounds (cf. Kiriloff, 1969) • Possible account • Cantonese T1[55] has a falling allotone [53] (Mathews & Yip, 1994) 22

Pinyin vs. Character • Production • %Err: Pinyin < character • Chinese character hinders L2 tone production • Perception • %Err: Pinyin > character • Chinese character facilitates L2 tone perception 23

Production Model (Chu, 2011) 24

Production • Pinyin • Directly access L2 phonological representations • May not reach the concept level • Chinese character • Sub-lexical route through the L1 phonological system • Corresponding rules may not have been correctly established 25

Perception Model (Chu, 2011) 26

Perception • Pinyin • Only need to reach L2 sub-lexical representation level • Chinese character • Need to go through L1 phonological system • However, pinyin %Err > character %Err • Possible account: top-down process in the Chinese character task 27

Conclusion 28

Conclusion • Comparing with Pinyin, Chinese character • Hinders tone production • Facilitates tone perception • Therefore, orthography plays an important role in L2 speech production and perception, especially when the learners ’s L1 and L2 share the same orthography system. 29

Limitations • Different task settings: • Pinyin perception (transcription) vs. Chinese character perception (2AFC) • Production (monosyllabic) vs. perception (disyllabic) • Stimuli not well controlled • Word frequency • Segmental features • Character strokes • Cantonese-Mandarin correspondence 31
