We'd like to remind readers that the responses to queries are usually best posted to the individual asking the question. That individual is then strongly encouraged to post a summary to the list. This policy was
instituted to help control the huge volume of mail on LINGUIST; so we would appreciate your cooperating with it whenever it seems appropriate.
In addition to posting a summary, we'd like to remind people that it is usually a good idea to personally thank those individuals who have taken the trouble to respond to the query.

I am a PhD student in Turkey. I have been working on my dissertation on the markedness differential hypothesis and the phonological errors of Turkish EFL learners. So far, I have been unable to find previous research done on the errors of L2 speakers in vowel and diphthong production. Can anyone refer me to useful resources please? I found many articles on epenthesis, syllable structure, stress patterns, and consonant deletion. However, I was unable to find anything on interlanguage studies conducted on vowel production.
