The interdental substitution in L2 phonology has been of issue in the L2 literature. Interdental fricatives are not common crosslinguistically. Therefore, they are hard to acquire for L2 learners whose L1s lack those sounds. Substitution with the sounds in their native languages is the strategy that learners take, however, the sounds used for substitution differ across languages. Although Japanese uses [s, z] for interdental substitution, languages like Thai use [t, d]. In the present study, I investigated the patterns of substitutions in different phonological environments by recording the speech of Japanese L2 learners of English. The result of the experiment showed that Japanese learners substitute interdentals with alveolar fricatives. However, they showed a different pattern for word-initial / /. They used [z] and [dz] for word-initial voiced interdentals. The appearance of [z] and [dz] was in free variation in the output. In this paper, I propose an Optimality Theoretic account for the interlanguage phonological phenomenon, and account for the patterns of substitutions as a result of L1 transfer.
