Sorry for the late response to you post. Your recording is quite clear. I don't think anyone would have any trouble at all understanding you. None.
If I had to pick out some very small points to work on, I would say that you should spend a little time working on TH (the, them). In addition, it sounded as if you struggled a bit with the LV combination in "twelve" and "delv
Thank you so much for your feedback. The fourth line should be "Knock at the door". Yes, that would be a big problem if my initial N's consistently sounds like L's. I guess I need to increase the nasalization of the consonant quite a lot. In my mother tongue, the n is only very slightly nasalized and that's why it is difficult for me.
