Question: is "dove" pronounced with a closed "e", and "dov'è" pronounced with an open "e"? If so, "dov'è" is pronounced wrong on the slow version. I reported it.
To further elaborate, "dove la tua famiglia?" is not a complete sentence as there is no verb; it would translate to "Where your family?" "Dove" is just "where" and "dov'è" is a contraction of "dove è" meaning "where is."
Where are your family cannot be a correct translation because it isn't grammatically corret in English. Family is a singular unit, although a family has many people. Where is your family is appropriate. Where are you parents and siblings is also correct. But family as one unit would be where is your family
