What is the difference between persona and speaker?

In literature, a persona is a character created by an author to narrate or tell a story. The persona may or may not reflect the author's own beliefs or experiences. On the other hand, the speaker is the voice behind the Words in a literary work, which may or may not be the same as the author or the persona. The speaker is the entity that is communicating with the audience, conveying thoughts, emotions, and ideas within the text.
