Nearly, but unless I'm speaking with family members / other people with thick southern accent, I try to keep the "u" sound present - though it's more like the French "u" than the "you" sound. So typically it sounds like 'ay-dub-yuez", with a short pause between the "yu" and "ez". It's the sound that would be in between "Suez" (like the canal) and "swez". Replacing the "yu" sound with the "ya", does indeed end up sounding like slightly elongated "yes".
