Final answer:
The term for speeches made by characters in a story that are all-seeing and all-knowing is 'omniscient,' referring to a narrator who knows everything about every character.
Step-by-step explanation:
The term for speeches made by characters in a story that are all-seeing and all-knowing is omniscient. An omniscient narrator observes and narrates from an all-knowing perspective, meaning they have full knowledge of the actions, thoughts, and feelings of each character in the story, regardless of whether the characters are present in the scene. This type of storytelling is not limited to the viewpoints of the characters involved and can offer a more objective and reliable narration. Austen and Martin Amis are examples of authors who have used this point of view in their works.
