The aria-label attribute is used to define a string that labels the current element. Use it in cases where a text label is not visible on the screen. If there is visible text labeling the element, use aria-labelledby instead.
This attribute can be used with any typical HTML element; it is not limited to elements that have an ARIA role assigned.

Possible effects on user agents and assistive technology
Examples
Example 1: Multiple Labels
In the example below, a button is styled to look like a typical "close" button, with an X in the middle. Since there is nothing indicating that the purpose of the button is to close the dialog, the aria-label attribute is used to provide the label to any assistive technologies.
<button aria-label="Close" onclick="myDialog.close()">X</button>
