Hope your meeting with HR goes well. I know all too well about being criticized for subjective perceptions of the tone of my (former) voice & tenor of my comments. Hope your HR meeting goes well and don't worry about "causing trouble". If you do not object, then everyone assumes the supervisor's misplaced critique is correct. In that vein, if HR does not help, escalate it up the HR chain or to your supervisor's supervisor. I found that being "more trouble than I was worth" a very effective workplace tool in getting supervisors to behave themselves. Good luck
