I believe my variety of English, General Australian, has "dark l", but I'm not sure.
I can't tell if I have it in my own idiolect or not.
It's pretty well accepted (I think) that it's hard to linguistically analyse your own speech.
In this case it could be tricky because in English dark l is an allophone of normal l (so it never contrasts directly as with a minimal pair).
Also I've largely lost my accent because of years of overseas travel and working with overseas travellers when I'm at home - so if I used to have it I'm still unsure whether I have it now.
So are there some methods or tricks a person can use to analyse their own various /l/ sounds, something like minimal pairs perhaps (I don't think there are exact minimal pairs).
How can a person analyse their own speech for presence of the "dark l" sound?
For testing dark /ɫ/, try doing palatography on yourself. You can do this with oil and chocolate powder, and a good digital camera with a flash. Paint your tongue with the chocolate oil, make the sound, and then snap a pic. Then wash, and paint your palate and check your tongue for results too.
