Do you know "nicos weg"? I am studying while watching the a1 video. There is a part that says "kein Problem" at the beginning of the video. However, no matter how slow you play it, your pronunciation cannot be heard accurately. The pronunciation I hear is 'en probiem' (sorry that I don't know the exact pronunciation symbol). I can't even hear "K" and "hinterlegen" also sounds "i:" rather than "e" in the "le" part. I've heard of these sounds from my German teacher. It's the sound of saying "i" for a long time and pronouncing "e" for a short time. Listening to various pronunciations, some people honestly pronounce "le". What's the standard pronunciation?
