[quote=misskate] The reviewer specifically said "Its not what you say its your TONE of voice". [/quote]

You should ask what is meant by your tone of voice. Does this person think you are being defensive of every remark? The intention of a critique of work should be to improve the result. You are doing commercial work and should be judged on the quality of that work, not on your voice.

Before you go to HR or any one else in your company you should talk to the person who said this and ask for an explanation and say that you were surprised by the comment and ask that it be striken from the record. Ask if there have been complaints from any of the other workers and explain what you wrote in your post about your voice. "words from the heart go to the heart."

Best wishes,
