Which sound device is used in these lines from the rime of the ancient mariner by samuel taylor coleridge to emphasize the importance of the albatross of the story?

Had to look for the missing details and here is my answer.

Based on the given lines which are taken from "The Rime of the Ancient Mariner” written by Samuel Taylor Coleridge, the sound device that is being used here in order to emphasize the significance of the Albatross to the story is the internal rhyme of “cross” and “Albatross”. Hope this helps.

The answer would be the internal rhyme of "cross" and "Albatross"

Hope this helps :)
