How Does the Sound Structure of the Language Affect Learning?

Danish has a tendency for speakers to swallow the end of syllables such that in many cases you will lose a lot of information. Children have problems figuring out where words begin and end when they happen in these kind of long sort of vowel-like sequences. And we found that that affects the ability to pick up vocabulary. Danish children are behind, for example, the kids learning Swedish or Norwegian or other European languages.
