本篇論文以聲學及聽覺感知方法研究台灣語者對於英語輔音串的學習,提出造成構音及聽覺感知障礙之成因,並探討發音與聽覺感知之間的關係。研究包括兩種類型的實驗,分別為發音實驗及聽覺感知實驗。
聲學實驗第一部分探討台灣語者學習英語輔音串的主要錯誤類型,並對語料作聲學分析。本實驗錄製八位語者(一位英語母語者,七位台灣語者)。實驗結果發現台灣語者最常出現的錯誤類型為元音加插以及流音代換(主要以類似/r/之音代換/l/);根據錯誤率的多寡,我們將台灣語者分為兩組人。統計結果顯示,有聲子音起首的輔音串 vs.無聲子音起首的輔音串以及包含/l/的輔音串vs.包含/r/的輔音串之間有顯著之差異。有聲子音起首輔音串以及包含/l/輔音串錯誤率較高,而差異皆見於兩組台灣語者。對於流音代換,我們提出了構音機制上的解釋:/l/需要兩個發音的gestures (stop closure and vocalic gesture),而相較之下/r/只需一個發音gesture (vocalic gesture),故在發含有/l/的輔音串時,台灣語者較難達到正確的發音位置。另一個可能性為,流音代換是受到前行塞音的發音方式所影響所致。
聲學實驗的第二部份為聲學研究。聲學研究針對塞音的嗓音起始時間(以下簡稱VOT)、流音長度(流音在音節中所占比率)、以及流音共振峰值(第一、第二、及第三共振峰)。分析結果顯示台灣語者塞音的VOT值與母語語者相似,而流音所占比率大於母語者。流音所占比率較大,我們推測為台灣語者需要較多的時間來完成輔音串的協同發音所致。共振峰值方面,結果顯示表現較好的台灣語者與母語者的值非常相似,而流音代換 (類似/r/之音取代/l/) 與英語的/r/的共振峰值在分布範圍以及平均值上皆非常接近。
聽覺感知實驗探討台灣語者如何聽辨英語CCV vs. C«CV兩類刺激項,本實驗包含指辨認(identification)實驗以及區辨(discrimination)實驗;共有二十八位台灣語者參與實驗。實驗結果顯示,受試者偶而會聽到虛幻元音(illusory vowel)以及將/l/以及/r/兩者混淆,但整體而言,台灣語者能夠區分英語CCV vs. C«CV兩類刺激項。此現象顯示母語的phonotactics在聽覺感知上並未扮演極重要角色,與Dupoux et al (1999)的結果不同。另外,實驗結果顯示,有聲子音起首的刺激項錯誤率大於無聲子音起首的刺激項;包含/l/的刺激項錯誤率大於包含/r/的刺激項。
本研究也發現構音與聽覺感知之間成正相關,受試者發音與聽覺實驗當中,傾向採用相同策略(元音加插或流音代換)。
本文為第一個探討台灣語者所發輔音串的聲學特性以及聽覺感知的研究,實驗結果使我們對非母語的輔音串發音以及聽覺感知有更深入的了解。希望本研究的結果能對英語的發音教學上能夠有所幫助及對在非母語聽覺感知之相關研究有所啟發。
The aim of this thesis is to investigate the influence of the native phonological system on the production and perception of non-native speech. In order to address this issue, three experiments were conducted to examine how Taiwan Mandarin (TM) speakers produce and perceive English word-initial consonant clusters.
The first experiment is an acoustic study of the production by TM speakers of English consonant clusters. Results show that the majority of the production corpus has been correctly produced. However, errors have been found: TM speakers employ multiple strategies and the most frequent strategies are vowel epenthesis between two consonants (CCV□C□CV) and liquid replacement (/bl/□/br/). Moreover, speakers are more accurate on some clusters than others. One interesting finding is that the liquid duration ratio of TM speakers is larger than that of the native speaker and the F3 value of replacement (/l/□/r/) is similar to that of /r/ (i.e. the characteristic feature of /r/ is low F3). The larger ratio of liquids implies that the TM speakers needed more time to coarticulate the articulatory gestures between segments. The lower F3 value may be due to the coarticulation of the previous stop consonants (coarticulation effects, i.e. labialization in /b/- and /p/-clusters and velarization in /g/- and /k/-clusters).
The second and third experiments explore the perception of TM speakers on English CCV clusters and their counterpart disyllabic C«CV stimuli. Results of perception experiments demonstrate that participants could perceptually distinguish CCV and C«CV stimuli. Occasionally, participants hear illusory vowels and misperceive /l/ for /r/. The results are not consistent with the prediction that native phonotactics plays an important role in non-native perception. Thus, it is suggested that, in addition to phonotactics, perceptual cues play substantial roles in the perception of non-native syllable structures.
Results of the present study support the notion that there exists a close relationship between production and perception despite the individual variations. Speakers with more production errors tend to misperceive the stimuli more frequently and they tend to employ the same strategies in both production and perception. Moreover, the fact that participants can produce and perceive English consonant clusters indicates that native phonotactics does not play a very important role in the non-native speech.
The results of these studies not only contribute to the understanding of the interactions of native and non-native languages on the levels of phonemes and phonotactics, explore the relationship between speech production and perception, but also provide implications for the data analyses and formulation of hypotheses for future studies.
