方音与连续变调

摘要

In the field of second language acquisition, the dialect research focus on the effects of first language to the second language segment from the phonological acquisition. This research attempts to through acoustic instruments, from the perspective of migration to study suprasegmental level of tone sandhi and dialect experience of the relationship, in order to reveal the spoken"dialect"in essence. The experimental results show that, the migration effect does exist in continuous tone level, the tone sandhi system of Putian dialect would interfere with Mandarin sandhi output, resulting in bilinguals speak with accents. At the same time as the Mandarin experience increases, the Putian dialect tone system changes, thus proving the necessity of suprasegmental level reverse migration.%　　在二语习得领域，对方音的研究，从语音习得层面的考察重点都集中在第一语言对第二语言音段层面的影响上。本研究试图通过声学手段，从迁移的角度考察超音段层面——连续变调与方言语音经验的关系，以揭示普通话口语中“方音”的本质。实验结果表明，迁移效应确实存在于连续变调层面，莆田方言的连续变调体系会干扰普通话连续变调的产出，导致双语者说话伴有口音。同时随着普通话经验的增加，莆田方言的变调体系发生变异，从而证明了超音段层面反向迁移的必然性。
