Is pronoun only used in inversion type?

No, you would say "Michael parle-t-il français ?" So, yes,you would use the pronoun in the inverted question. -- Chris (not a native speaker)

Hi Sivavathana,

As Chris rightly points out, in this case you have to use a pronoun as well as a name.

Michael, parle-t-il français?

If too much of a mouthful you can use "est-ce-que" and you won't need the additional pronoun.

Est-ce -que Michael parle français? 

Hope this helps!
