You don't need ARIA attributes in such cases. They are meant to be used
for providing information that programs cannot infer from normal HTML
markup.

First rule of ARIA use in the working draft "Using WAI-ARIA in HTML" is:
"If you can use a native HTML element [HTML5] or attribute with the
semantics and behaviour you require already built in, instead of
re-purposing an element and adding an ARIA role, state or property to
make it accessible, then do so."
http://www.w3.org/TR/aria-in-html/#first-rule-of-aria-use

The <label> element is an HTML element for the purpose of specifying a
label for a control. When you can use it, you do not need to duplicate
this with aria-labeledby.
