The author's voice is implicit in all writing, even technical writing. It is the expression of the writer's attitude toward audience, subject matter, and self. Effective use of voice is made possible by recognizing the three roles of the technical writer: transmitter, translator, and author. As a transmitter, the writer must consciously apply an appropriate voice, a voice in which the message is not overshadowed by the author's presence. As a translator, the writer must reflect empathic understanding of the audience's needs. In some cases, the writer acts as an author, making his or her voice as important as the information communicated. While perhaps not assuming all three roles, a technical writer can communicate more effectively by recognizing the importance of voice in writing. (MM)
