Answer 2

From fictionwriting.about.com: Voice has two meanings as it concerns creative writers:

Voice is the author's style, the quality that makes his or her writing unique, and which conveys the author's attitude, personality, and character
OR
Voice is the characteristic speech and thought patterns of a first-person narrator; a persona. Because voice has so much to do with the reader's experience of a work of literature, it is one of the most important elements of a piece of writing.
