I'm going to assume you're Swedish. I have a question for you: is the phonetic feature "laryngealisation"(aka vocal fry or 'creaky voice') common there? I noticed it a few times now, when I was in Sweden and watching some Swedish movies. It is prevelant among many younger female Americans and you'll find more literature on it there. But I've noticed it among Swedes and Danes when speaking Swedish and Danish. EDIT: I just found it is a feature in Danish known as "stød",  but that's more adding a glottal stop, not creaky voice.
