Currently, Waze expects voice commands in the language of the country that I am in. It disregards that the phone language. (English in my case, therefore, waze interface is also in English). I am, however, in Portugal. Therefore Waze voice commands are expected in Portuguese.

Consider the new implementation on no roaming fees in Europe. When I drive to Spain, I am expected to speak Spanish. When I go to Croatia, I am expected to speak Croatian.

Solve this by setting the voice language to the language of the phone (or waze). Otherwise Waze voice commands are useless.
