When Jesus was baptized, those present heard the following:
“And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.” (Matt. 3:17)
A similar event occurred when Jesus appeared to the Nephites:
“Behold my Beloved Son, in whom I am well pleased, in whom I have glorified my name—hear ye him.” (3 Ne. 11:7)
Typically, we assign the words to Heavenly Father, although in both cases the text doesn’t indicate who the speaker is. We can certainly infer that the speaker is a parent of Jesus, given the use of “my beloved Son”.
Even the most widespread First Vision account doesn’t mention specifically that it was God the Father introducing Jesus:
“When the light rested upon me I saw two personages, whose brightness and glory defy all description, standing above me in the air. One of them spake unto me, calling me by name and said, pointing to the other—This is My Beloved Son. Hear Him!” (JS–H 1:17)
If the texts are silent on who the actual person was speaking, does that mean we are projecting our own biases onto the story?
What if it wasn’t God the Father who introduced Jesus on these 3 occasions? What if it was God the Mother instead? The texts certainly don’t preclude Heavenly Mother from being the speaker.
If Heavenly Mother did speak at Jesus’s baptism, if she did introduce him to the Nephites, if she did appear to Joseph Smith, how would that change our perception of her and the role she plays in the eternities?
