How does Oneness Pentecostalism interpret Matthew 3:17?

[**Matthew 3:16-17 NIV**](http://www.biblegateway.com/passage/?search=Matthew+3:13-17&version=NIV) >16 As soon as **Jesus** was baptized, he went up out of the water. At that moment heaven was opened, and he saw the **Spirit of God** descending like a dove and alighting on him. > >17 And a **voice from heaven said**, “This is my Son, whom I love; with him I am well pleased.” If there is no distinction between the Father and the Son, as Oneness adherents believe, how do they explain the voice from heaven?
