Comparative Study on Coda/m/ Transfer Effect Between With-coda/m/ Dialect Speakers and Without-coda/m/ Dialect Speakers

There are both positive transfer and negative transfer in second language acquisition (SLA). The purpose of this paper is to explore the ways in which sharing features of L1 and L2 can contribute to L2 learning, while different features can negatively affect L2 learning. The listening test on coda/m/ was carried out on the Chinese language subjects of with-coda/m/ dialects and without-coda/m/ dialects. The results showed that: With-coda/m/ dialect speakers have no significant advantage over general coda/m/ perception over Without-coda/m/ dialect speakers. However, with-coda/m/ dialect speakers have significant advantage over the other group on certain vowel-coda/m/ sets that exist in their L1. This work provides some inspiration for English teaching, and also deepens the relevant theories of second language acquisition. In addition, for learners with specific speech disorders, this study helps to identify the source of the problem, provide data support for the field of speech pathology, and guide the design of more accurate intervention and treatment programs for speech disorders.
