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!
Some might think that the audio portion of a video takes a backseat to the visual portions, but that’s not true. Most video watchers note that they are more likely to stop watching a video with bad audio vs. lower-quality video. In fact, a recent TechSmith study of video viewing habits showed that more than 25% of video viewers watched a video all the way through because the audio was good — more than those who said professional video style was most important.
Before you get down to the nitty-gritty, though, I recommend doing a test recording to ensure your equipment works properly and your audio levels are strong. You don’t need to record the entire script, but a few paragraphs will give you enough to ensure that the audio is clear, at an appropriate level, and doesn’t include any stray or ambient noises.
Fortunately, the internet has made this easier and more open. Most businesses have a logo, brand and a website. This forms the basis of how people get to know them. As a voice-over business you need to recognise that you need to market yourself. This involves ensuring you get your brand, your business, in front of the right people. Marketing though is also about building relationships with customers, not just selling to them. The more customers that use you on a regular basis the more money you can earn and the easier it becomes to achieve a good income.
"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.”
There are two main priorities in voiceover work: the message that you're being asked to convey; and invisibility — by which I mean you never want people to notice your voice. This might sound counter‑intuitive. After all, why not make your voice sound great? Well, you need the listener to focus on the message your client is paying you to get across, rather than your voice itself, so it needs to sound natural. Even for tag lines, where you might think a fuller, warmer, more compressed (or whatever) voice would be appropriate, the production house will often want to perform EQ and compression themselves. This lesson took me a long time to learn, but my clients are much happier when I send them a nice, dry recording. I simply remind myself that I'm supplying the raw material for them to add to their mix, and letting them make their magic.
Voice over is a production technique where a voice that is not part of the narrative is heard over the action. It’s often used in movies, TV shows, plays, or other presentations. Voice over is an effective way to convey information that doesn’t naturally fit into the plot or the other visual elements that are occurring. Voice over work is read by a voice actor who reads from a script, and it is added to the other elements during production. 

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.
