  No, we don’t have the technology to do something like that, and even if we did it would talk some class of supervillain/mad scientist to even try!

  what a great question, I think it would be impossible but let’s imagine being trapped in an animals body because you would not be able to speak without the proper vocal cords as well, how would you communicate, and if we put an animals brain in a human body with vocal cords would it learn to speak?! I am not sure what animals skull would be the right size for a human brain either.
