Rigidly formal; "a starchy manner"; "the letter was stiff and formal"; "his prose has a buckram quality"

I had never used the word "metallic" in connection with the sound of a human being’s voice until I heard a sermon delivered by a young priest in rural Ohio. At the time I thought it uncomfortable that a preacher’s job would rely on their charisma, but it was a not-so-subtle secret that this person was auditioning for a job as community preacher and man of God. I had never imagined that jobs like this came with interviews and test sermons. It seemed like a role one was born into or otherwise acquired, but not a job one aspired to. That is not to suggest that the job is undesirable, but to say that it seemed like a position devoid of corporate machinations and approval processes.
