They received the total of 20 hours of pronunciation instruction. The participants read a diagnostic passage before and immediately after the instruction. Ten Japanese EFL students were employed as a control group. Ten native speakers of English rated the comprehensibility (ease of understanding) and the accentedness (how different from NS's norms) of the utterances produced before and after the instruction by the learners in the experimental and the control groups. The results showed that the experimental group improved in terms of comprehensibility while the control did not. As for accentedness, neither group showed any improvement.born digitalmasters thesesengCopyright and other restrictions may apply. User is responsible for compliance with all applicable laws.
