When Jesus was on the earth on what two occasions did God speak directly from heaven?

The New Testament records God speaking from heaven on three occasions:

Jesus' baptism: Matthew 3:17 - And suddenly a voice came from heaven, saying, "This is My beloved Son, in whom I am well pleased."

The Transfiguration: Matthew 17:5 - While he was still speaking, behold, a bright cloud overshadowed them; and suddenly a voice came out of the cloud, saying, "This is My beloved Son, in whom I am well pleased. Hear Him!"

Following Jesus' triumphal entry into Jerusalem: John 12:28 - "Father, glorify Your name." Then a voice came from heaven, saying, "I have both glorified it and will glorify it again."
