She speaks very fast for an app designed to teach people with a low knowledge of the language.
I agree, but then again I think it's important to hear the language as it is spoken by natives, because most of the time people speak very fast and some words change their sound when they are pronounced almost together.
We also have the advantage of having "her" repeat it over and over until we figure our each word...but it might also be good to hear each word separately...
Slight correct - either, depending on the genders of everyone in the group of "we" - use grammatical feminine when everyone in the "we" is feminine.
Your problem is that you try to translate every single word. Just learn it as it is. As a kid.
