/ɵ/

Continued from User talk:Xyzzyva.

Well, I acquired the habit of using /ɵ/ from Wikipedia, where it's used for those unstressed vowels that vary between /ə/ and /oʊ/ (or somewhere between) for different speakers. The note at WP:IPA for English:

Pronounced [ə] in many dialects, and [ɵw] or [əw] before another vowel, as in cooperate. Sometimes pronounced as a full /oʊ/, especially in careful speech. (Bolinger 1989) Usually transcribed as /ə(ʊ)/ (or similar ways of showing variation between /əʊ/ and /ə/) in British dictionaries.

I'm not sure how this fits in to Wiktionary's pronunciation policies.

Okay, I see. Wiktionary has few guidelines concerning pronunciation, and nothing on this specifically, so there's nothing wrong with it.
