I would like to see an example where /o/ too induces affrication, if you have one?.    From Wordnik.com.  [Linear A treatment of consonant clusters] Reference

If it were vowel height/closedness that caused the affrication, then the affricates would be the same.    From Wordnik.com.  [Concern trolls and the Etruscan bilabial 'f'] Reference

This leaves the affrication of Japanese alveo-dental stops before /u/ to be explained by some other phenomenon.    From Wordnik.com.  [Concern trolls and the Etruscan bilabial 'f'] Reference

I'm merely exploring a more general phenomenon here, one in which stops neighbouring closed vowels or semivowels are universally more prone to affrication.    From Wordnik.com.  [Concern trolls and the Etruscan bilabial 'f'] Reference

The Japanese facts could just as well be explained as a similar case of affrication before high vowels with a secondary process of palatalisation before /i/.    From Wordnik.com.  [Concern trolls and the Etruscan bilabial 'f'] Reference

Every single francophone initially pronounces it like soldier but without the affrication on the d the change the i makes, and everyone corrects them to the l-less variant.    From Wordnik.com.  [languagehat.com: SOLDER.] Reference

Independantly, tso being the regular realization of /to/ doesn't fly as a free assumption either — a non-close back vowel is about the least likely to trigger affrication.    From Wordnik.com.  [Linear A treatment of consonant clusters] Reference

Anita is disturbed but Michael comminates that he will reserve her case tomorrow for the ordinary Guglielmus even if she should practise a pious fraud during affrication which, from experience, she knows (according to Wadding), to be leading to nullity.    From Wordnik.com.  [Finnegans Wake] Reference

Notice also that the common feature in Japanese /i/ and /u/, ie. the vowels inducing affrication, is precisely +high.    From Wordnik.com.  [Linear A treatment of consonant clusters] Reference

Previously I was explaining that friction neighbours a -front vowel in Japanese in response to your statement that "a non-close back vowel is about the least likely to trigger affrication" but I realize that I overlooked the important word "non-close" which is evidently against my proposal of /to/ being affricated, not against /tu/.    From Wordnik.com.  [Linear A treatment of consonant clusters] Reference
