I have observed some English speakers in North America who seem to produce this assimilation in words like running /ˈrʌnɪŋ/ (as [ˈrʌnin]) or winning /ˈwɪnɪŋ/ (as [ˈwɪnin]). I'm specifically interested in when the final vowel becomes [i] or [iː] and not /ɪ/ (as in some Southern American English accents, which produce [ˈrʌnɪn] and [ˈwɪnɪn]).
Is this a regional accent?
I found some additional anecdotal discussion at the following links:
- Antimoon (a site for English learners)
- Unilang
- Yahoo Answers
Before ng, it shifts towards the vowel in beam, bean Example: think sounds like theenk " http://www.stanford.edu/~eckert/vowels.html
