Voice reels and demos are the same thing. In the UK we tend to say ‘reel’, but in the USA ‘demo’ is more widely used. A demo is usually around one minute long and includes clips of voiceover work either recorded for the purpose of the reel or extracted from paid jobs. It’s like a VO’s resume. It is designed to show off your voice and give the listener an idea of the different styles you can deliver. There are many different types of demos and you can have as many as you like, but the most important one, and the one that agents prefer, is the commercial reel followed by a narration reel. You don’t need to have lots of reels. It’s always better to have quality over quantity. It is vital to get your reel professionally produced as you will be sending it to producers, casting directors and agents and they will hear if it has been produced poorly. It is important to get training before you get your voice reel made. This is one of the biggest mistakes people make. You need to understand your range and how to best utilise your voice in a studio. Do not let a voice reel producer push you to do something you aren’t comfortable with in the studio because you may need to be able to recreate it at short notice.
