Translation:If you were with me the sun would shine.
The recorded sentence is not clear enough, it was hard for me to understand איתי from the playback. And I am Israeli
Just my opinion: If THIS phrase were pronounced a bit slower it would be easier to learn to pronounce the words correctly...but most of the time the mail voice is very good! (Maybe the female voice could slow down more often too?). I think the most difficult words are the words with two juds after one another. Always unsure how to pronounce them...
Since modern hebrew does away with vowels, it often uses a י or a ו as replacements. So to specify a 'y' sound, sometimes you have to put two yuds יי. For example the difference between עיירה and עירייה
Town - iyara - עיירה
Municipality - iriya - עירייה
You see the Y sound follows the double yud.
