His speaking voice, a gruff husky tenor, added to the impression of fractiousness he conveyed
Nicks description of Tom’s voice is suggestive that Tom is aggressive and ill tempered. He says his voice is “gruff husky tenor”—not terribly deep, but intimidating nonetheless. The use of “fractiousness” describes how easily irritated he is. He shows his simple irritation when he hits Myrtle later in The Great Gatsby.
