I think it is usually used in front of people's names. In this case "ia" can also mean "this" or "that", so they put ʻo to show that they mean "he", "she", or "it".
The way the female audio translater was TOTALLY differebt than how its spelled. She said Pehea Oia (Pehea Oiya). Isn't it supposed to be pronounced "Pehea O Eeyah"?
It accepted ,"How is she?" I hope this also accepts, "How is it?" (in regard to a noun).
