The pronounciation of oranje is wrong, sounds like oeranje.
You are right, the voice didn't say "Oranje" very well
Ziet je de oranje borden? Is that a proper sentence?
Zie je de oranje borden? *
The verb used with the subject pronoun "je" in an interrogative sentence drops its 't'.
Doe je het? (Are you doing it?)
Ken je deze persoon? (Do you know this person?)
