I've puzzled over my pronunciation of "ul" in words like pull, culture, adult and multiple. The dictionary says it should be /ʌ/. I heard a Canadian teacher pronounce "culture" /'kol tʃɘr/. My pronunciation is between /o/ and /ʌ/, so I think it's a mid back rounded vowel: /o̞/.
Am I the only American who pronounces "ul" like this? For your reference, as an ESL teacher, I generally speak General American, have mostly lived in Northern California, but also in western North Carolina for four years.
