Exploring a Phonological Process Approach to Adult Pronunciation Training.

Purpose: The production of speech sound classes in adult language learners is affected by (a) interference between the native language and the target language and (b) speaker variables such as time speaking English. In this article, we demonstrate how phonological process analysis, an approach typically used in child speech, can be used to characterize adult target language phonological learning.

Method: Sentences produced by 2 adult Japanese English language learners were transcribed and coded for phoneme accuracy and analyzed according to the percent occurrence of phonological processes. The results were interpreted relative to a contrastive analysis between Japanese and English phonetic inventories and developmental norms for monolingual English children.

Results: In this pilot study, common consonant processes included vocalization, final consonant devoicing, and cluster reduction. These are processes commonly observed in the speech of children who are typically developing.

Conclusions: The process analysis can inform clinical approaches to pronunciation training in adult English language learners. For example, the cycles approach (Hodson & Paden, 1981) may provide more clinical efficacy than an articulatory approach in which phonemes are targeted individually. In addition, a process analysis can enable clinicians to examine the principles of within-class and across-class generalization in adult pronunciation instruction.
