Yes, if you would have had a question mark. The exclamation mark makes the difference.
The more i learn words that are similar in English, the more my spelling in both jitters
It's quite common when learning languages that are closely related. I've had the same problem with English/Swedish/Dutch/German. It's all a Germanic mess sometimes.
I don't know if this is supposed to happen, but I always get new words whenever I am strengthening them, and then I have to spell them out using only sound which is really tricky.
from what i experienced so far, it is quite common. For once, words learned in new lesson have an impact on older lessons. Besides that, the strengthening lessons often use different questions then what the lessons has thrown at you before. I started to see the lessons as vacabulary learning and the strengthening as a way to test it with different question. however, every then and when new words are introduced that are not marked as new aswell. It can aswell to happen to have multiple new words in question - non of them marked as new. It is verry confusing, however, i do not think that is all so bad, as the way you learn from these sentances does not verry from the way you learn it elsewise.
Yes, you should. The first syllable of the word "karriär" has the short a-sound as in "katt" (cat) and the second one has a long ä-sound as in the word "är" (is).
Really? I think the TTS is getting this very much right. I hear a distinct difference.
Adding my 2 cents that it does sound like karriar rather than karriär - obviously we're not native speakers, but I'm usually able to hear the vowels clearly. NB this is when listening to the phrase as a whole.
