    I'm Dawn and I record all my voiceovers in my natural British accent I have a warm and professional tone but can alter my style to suit your needs. Whether you need a professional public service announcement, an energetic and upbeat sales tone, a natural girl next door voice, I can do them all. I love recording and have traveled all over the world with my work. I would love to work with you on your voice over needs and you can order from me with 100% confidence. I have my own studio that I work in every day and am able to deliver all orders as High Quality MP3 or Wav files. I am also able to do a variety of extras, such as split the files into separate files, add royalty free music, match the voiceover to pre-existing video, correct grammatical errors in scripts and much more. All my previous clients are very happy with my work and with the professional and timely way in which we communicated. If you have any questions or would like a sample please send me a message Thanks! Dawn ít hơn
