Final answer:
The phrase "Her voice is full of money" is a metaphor, which compares two unlike things directly, suggesting one has the qualities of the other. The second phrase involves rhythm and a potential metaphorical charm.
Step-by-step explanation:
The literary devices used in the phrases "Her voice is full of money" and "that was the inexhaustible charm that rose and fell in it" are primarily examples of metaphor. A metaphor is a direct comparison between two unlike things, suggesting they are the same without using "like" or "as". In this case, the speaker is not saying her voice literally contains currency, but is metaphorically suggesting that her voice has qualities that evoke the sense of wealth. The phrase "that was the inexhaustible charm that rose and fell in it" does not neatly fit simile, personification, or alliteration, but it does involve rhythm and could hint at a metaphorical charm.
