It depends on who you're speaking with:
"parles-tu français?" (is said to a friend, someone "familiar" or someone younger)
"vous-parlez français?" (someone older, of higher position - like an elder, boss or teacher)
"tu parles français" and "vous parlez français" are also accepted.
To ask if French is generally somewhere (like in a store or a country) you can ask "On parle français ici?"
