Again, Revelation 21:6 is the Father speaking, not Jesus.
And Revelation 22:13 is an Angel speaking a message from the Father.
You are incorrect. To put my original verse into context, the answer as to who the speaker is can be found in the following verses.
Revelation of John 1:8: I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.
Revelation of John 1:9: I John, who also am your brother, and companion in tribulation, and in the kingdom and patience of Jesus Christ, was in the isle that is called Patmos, for the word of God, and for the testimony of Jesus Christ.
Revelation of John 1:10: I was in the Spirit on the Lord’s day, and heard behind me a great voice, as of a trumpet,
Revelation of John 1:11: Saying, I am Alpha and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea.
Revelation of John 1:12: And I turned to see the voice that spake with me. And being turned, I saw seven golden candlesticks;
Revelation of John 1:13: And in the midst of the seven candlesticks one like unto the Son of man, clothed with a garment down to the foot, and girt about the paps with a golden girdle.
Revelation of John 1:14: His head and his hairs were white like wool, as white as snow; and his eyes were as a flame of fire;
Revelation of John 1:15: And his feet like unto fine brass, as if they burned in a furnace; and his voice as the sound of many waters.
Revelation of John 1:16: And he had in his right hand seven stars: and out of his mouth went a sharp twoedged sword: and his countenance was as the sun shineth in his strength.
Revelation of John 1:17: And when I saw him, I fell at his feet as dead. And he laid his right hand upon me, saying unto me, Fear not; I am the first and the last:
Revelation of John 1:18: I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death.
Now, you may argue to the cows come home that this was rewritten to suit us
misguided christians' bias, which is a commonly touted rebuttal (
and a weak one at that), but you have no latitude to state that Jesus was not the one described as John's interlocutor, otherwise it opens up a new host of questions of which I will undoubtedly wit the use of the scriptures entangle you. End of discussion.

The Speaker Confusion problem is rife for those using Revelation to promote the Trinity.
Examining the Trinity: AO - Speaker Confusion
I wouldn't know anything about it. I'm not a trinitarian coincidentally.
