Can I attune a circlet of human perfection to my animated skeletons allowing them to blend in and speak?

For those unfamiliar, a Circlet of Human Perfection is a Dungeon of the Mad Mage item that reads:

The Circlet of Human Perfection transforms its attuned wearer into an attractive human of average height and weight. The circlet chooses the physical characteristics of the form, such as age, gender, skin color, hair color, and voice. Except for size, the wearer’s statistics and racial traits don’t change, nor do items worn or carried by the wearer. Removing the circlet ends the effect.

If I allow my skeleton created with Animate Dead to attune to this item will they be able to blend in perfectly? What about their ability to speak?

The language trait for skeleton reads that you can’t speak, but the circlet reads that you gain the voice of a human. Do the racial traits staying the same supersede the gaining of the voice?
