::::"Independent experience and testing" don't count for much here, but I can provide a few references: 
 *: At 0:36 the held /ɪ/ is clearly the end of the syllable, and the next begins with /ŋ/. 
 *: Not too sure about 0:06, but his many "singing in the rain"s all divide on the /ɪ/. However, these are both sung sound samples where the tendency may be to end the syllable with a vowel. 
 *: The official audio file from Wiktionary. I'm not too sure about this one; I can make the velar nasal switch between onset and coda like the famous Rubin vase. I can't really vouch for more audio files as "singing" is the only entry on this page that has been recorded. |
