Translation:The teacher is giving the students an education.
I'm guessing the voice can't distinguish between 'gir'(verb) and 'gir'(noun) without context.
In this context, 'gir' meant "gives/is giving', and should be pronounced similar yo 'yir''. (This is often the case with gi-)
'et gir' can however also mean 'a gear', in which case it is pronounced 'gir' (with a g-sound).
I had this in the version where you are given a choice of words, and you have to click on the right words in the correct order, but there was no "gives" or "is giving", so I had to do it by clicking on "Use Keyboard"!
Teachers may have assistants to do the paperwork where you live, but not in my country. Here a lecturer usually is employed by a university and teaches students, whereas a teacher works in schools for pupils between ages 5 and 17. Student and pupil are almost synonyms here. But I think the actual separation is much like Norwegian.
