Voiceover artists or narrators are professionals who not only read your book out loud, but also have the skill to bring the text to life by using the right nuances, emphasizing certain words, adding subtle pauses and touches, such as laughter or sarcasm.
Tip #1: Make sure the narrator agrees to a full-buyout which means that you, as the author, are the one owning the rights to the recording. Otherwise, be prepared to pay the narrator any royalties derived from future sales of the audio book.
Tip #2: You can use narrators or voice over artists also for your book promos or book trailers videos.
