【摘要】：在聽到一種全新的語言(L3)時,人們常常使用自己熟悉的母語(L1)語音編碼去表征L3當(dāng)中新異的語音,因此常常導(dǎo)致誤解和口音等問題。本研究使用信號檢測論方法,設(shè)計以上海話為信號刺激,各種聲母近似、韻母相同的語音為噪音的信號檢測任務(wù),用辨別力d’指標(biāo)來研究北方官話區(qū)被試表征上海話音素的方式對分辨任務(wù)表現(xiàn)的影響。結(jié)果表明,北方官話區(qū)被試辨別力顯著低于滬語區(qū)被試,即使經(jīng)過跟讀學(xué)習(xí),滬語區(qū)被試的辨別力仍然顯著高于北方官話區(qū)被試。在未經(jīng)跟讀的情況下,滬語區(qū)被試對于單字反應(yīng)標(biāo)準(zhǔn)更保守慎重,對詞語更隨意冒險,對單字的辨別力也高于詞語。而北方官話區(qū)被試則對于詞語的辨別力高于單字的辨別力。對于單字和詞語檢測任務(wù),北方官話區(qū)被試對于詞語的辨別力高于單字的辨別力。對于三種信噪組合來說,滬語區(qū)被試的辨別力相近,其中對英語音素信噪組合的辨別力稍低,跟讀學(xué)習(xí)后,滬語區(qū)被試對于三種信噪組合的辨別力均上升。而北方官話區(qū)被試對普通話音素的信噪組合具有較高的辨別力,而對于英語音素和滬語獨有音素的信噪組合則辨別力極低。經(jīng)過跟讀學(xué)習(xí)之后,北方官話區(qū)被試對于英語音素的信噪組合辨別力會有所提升,而對于滬語獨有音素的信噪組合即使經(jīng)過跟讀學(xué)習(xí),也無法獲得提升。
[Abstract]:When we hear a new language (L3), people often use their familiar native language L1) to represent the new and different pronunciation in L3, which often leads to misunderstanding and accent problems. In this study, using the signal detection theory method, we designed the signal detection task with Shanghai dialect as the signal stimulus, all kinds of consonant approximations and the same vowel voice as the noise signal detection task. The influence of phonemes in northern Mandarin area on the performance of discrimination task was studied by discriminant d'index. The results show that the differentiation ability of the participants in the northern Mandarin area is significantly lower than that in the Shanghai dialect area, and even after reading and learning, the discrimination ability of the participants in the Shanghai dialect area is still significantly higher than that in the northern Mandarin area. In the case of unfollowed, the subjects in the Shanghai language area were more cautious about the standard of response to words, more casual in taking risks to words, and higher in discriminating words than words. In the northern Mandarin area, the discriminating power of words is higher than that of single word. For the task of word and word detection, the discrimination of words in Northern Mandarin area is higher than that of single word. For the three kinds of signal-noise combinations, the discrimination ability of the Shanghai-speaking area subjects was similar, and the discrimination ability of the English phoneme signal-noise combination was slightly lower, and the discrimination ability of the Shanghai-speaking area participants for the three kinds of signal-noise combination increased after following the reading study. The participants in the northern Mandarin area have a higher discriminating ability to the phoneme combination of Putonghua, but to the English phoneme and the Shanghai unique phoneme combination, the discrimination ability is very low. After following reading study, the northern Mandarin area participants' ability to distinguish the English phonemes will be improved, but for the unique phonemes in Shanghai language, they can not be improved even after learning to follow the reading.
