If a client likes your demo, they may invite you to audition. In the 21st century, you can download the audition script, record the audition at home, and then send the results to your client over the Internet. Prepare yourself for a life of constant auditions: Even successful voice pros may do many more auditions than actual jobs. But if enough jobs come your way, it's worth it.
The annual income of a voice talent varies greatly from person to person and from year to year. When you’re just starting out most of what you earn from voice over work should be reinvested into your studio, demos, and marketing efforts, so at this stage you will need a second job to support your daily living expenses. Once you start building a portfolio of clients, you’ll see your regular earnings grow and will really start to get a feel for the potential your voice over business has. In time, you’ll be enjoying a satisfying career.

The advice we present here is tried, tested, and true. Peter Dickson is the foremost leading professional voice actor in the UK known for voicing the X-Factor, Britain’s Got Talent, Live at the Apollo, The London 2012 Olympic Games and countless brand commercials. In a stellar  career spanning 40 years, he has worked on over 120 TV shows and series, many of them award winning, been a promo voice on 60 TV and Radio channels around the world, been a featured voice actor on 30 AAA game titles, and voiced in excess of 30,000 radio and TV commercials!

You start off each job as a producer, consulting your client and getting briefed on the project at hand. Then you become an engineer, dealing with recording gear and software, setting the mic position and levels. Next, you step up to the mic as an actor, bringing the script off the page and connecting with the listener. Meanwhile, the director in you sits behind the metaphorical glass, making sure the actor doesn't mispronounce a word or stumble through a passage of text. Then you're an editor, cleaning up the best take and sending the resulting audio to your client. You need to be able to perform all of these roles to a high standard, and the better you are at each, the more your business will prosper.

In late 2009, my wife Simone received an email from Prague in the Czech Republic. The sender, Mirek Jirku, was heading up a project to record voice messages for the foreign‑language versions of the latest Avast! anti‑virus software. Mirek sent us eight messages to be recorded, specified the fee and deadline, and requested a slow, friendly read. He asked us to send separate stereo MP3 files (at 160kbps or higher quality) for each message, specified that we'd have to sign a non‑disclosure agreement before recording, that we'd need to invoice afterwards, and that he'd pay via a wire transfer instead of PayPal (which is often used for international payments).
"Ideally the talent should be seated, staying on axis, approximately a foot away from the mic, which should be angled back from the face a bit, not parallel to it. You'll need to see what angle provides the best results, usually a few degrees off from parallel works great — and located between the forehead and the nose, not directly in line with the mouth. This will help with plosives, mouth noise, and some other issues. Movement in the booth should be limited, as the microphone is likely to pick up arms flailing, hands rubbing, page turns, stomach growling, and so on. Keep the levels consistent, moving closer if the scene calls for a whisper, or moving back for a loud voice or scream. A well‑versed narrator is capable of delivering a dynamic performance without creating dynamic levels.”
I use the Adobe Audition package to edit my own voiceover work, but the techniques described below can be used in most audio‑editing software. Start by saving a new version of your original recording. (I keep the name of the file the same, but change the extension from _original to _edit.) Next, I'll turn my attention to the end of the recording, where I stepped away from the mic after the second take and recorded about 10 seconds of silence. Although processing is usually kept to a minimum, dealing with sibilance is important, and Eiosis' De‑esser plug‑in is much more precise than most.Wearing headphones, I can zoom in on this 'silence', turn up the volume, and listen for any background noise. If I notice any constant noise seeping into the recording, I may consider using Adobe Audition's noise‑reduction tool to capture a one‑ or two‑second profile of the silence, and then reduce the offending noise by about 75 percent throughout the recording. I should stress that this is rarely needed, and it's always a last resort, because such processing can generate swirly, metallic artifacts that draw more attention to themselves than the noise you intended to eliminate! But it's good to listen for such issues with fresh ears at the start of your editing session. If you find yourself using noise‑reduction often, that's a sign that you should find a better place to record, or improve the isolation of the space you've chosen. Don't forget that there are other ways to deal with some noise: often, a high‑pass filter is all you will need to clean up a recording, for example. Also remember that if your recording is to be mixed with music, slight background noise won't be noticeable, and that the more exposed your voice in the end product, the more problematic noise will become.
Important: Use headphones to check the audio quality of your test recording. Your computer speakers will not be good enough for this. Headphones allow you to listen closely to ensure clear audio. Obviously, you want the audio to sound good on even the cheapest speaker, but you will be much happier if you use headphones. Remember, a good portion of your video viewers will listen this way, so you want to be sure they’ll have an optimal experience.

There are lots of ways to get voice acting work, from online sites such as Bodalgo.com, Mandy.com, Voice123 and Voices.com. These are known as pay to play sites. They have lots of opportunities for you to audition, but it is highly competitive. Looking locally for businesses, including radio stations, that need voiceover is also a good way to start.
Perhaps you come from a corporate business background, but you have a remarkable capacity for accents and original character voices, or you’ve been in radio and broadcasting for a number of years. If you’re an actor looking to expand your employment opportunities, mastering voiceover is imperative considering it’s required in every manner of recorded media: film, TV, animation, games, corporate industrials, and commercials. Whatever your specific experience has been to date, getting started in voiceover most often requires the following:
As editor, you need to turn the raw recording into the final version of the file you'll be sending to your client. Editing during a recording session can be problematic, and particularly so if you're recording in a domestic environment. How can you expect to hear the drone of the dishwasher ruining your recording if the dishwasher is still running as you edit? I'll look in more detail at setting up a voiceover recording studio next time, but for now, if recording in a separate room or isolated booth isn't an option, at least try to edit the file the following morning (or maybe at night) when there's less noise around — because hearing your recording with a fresh ear and in a quieter environment will help you to make better editing decisions, and will reveal noises that slipped your attention earlier.
