Good news! I finally finished my MA thesis and turned it in this week. It’s titled Computerized Training in /r/-/l/ and Stress Distinctions for Japanese Learners. I’ll be defending it in early February. If you’re interested in reading it, you can download the PDF right here. If you’re busy and just want to know how it went, basically I showed that Japanese students can learn stress distinctions from a simple program, and that video doesn’t really help them. I also confirmed the previous results that many other researches have found, that Japanese learners can acquire /r/-/l/ distinction through computer training.
You can try out the program online here, if you like.
