"It's always best to address these issues while recording. If a person is sibilant and/or 'mouthy' (clicks, pops, whistles), there are ways to lessen and sometimes eliminate the issues all together: juice from green apples, rinsing with water, repositioning the mic and pop‑filter, and adjusting his or her way of breathing. If there are still issues, I edit out as many of the problems as possible. Often, I redraw the waveform to get rid of issues, or use plug‑ins. We have just started to make use of Izotope's RX 2 Advanced, which works wonders on clicks, crackles, and the like. What I can't fix we try to have the talent come back in to do pick‑ups.”
A better, more natural-sounding way to clean up a voice recording, though, is to paste in strips of 'silence' that showcase your home studio at its best. To do this, wake up early (ie. when your house is quiet), turn on your gear and set your levels for a normal job. Then record a full minute of silence at whatever bit depths and sample rates you're likely to be using. Repeat this process for each different mic you use, and save each file in a folder titled Room Tones, or something similarly suitable.

Get your computer out of the room. Your microphone will pick up fan noise from your computer. Unless you have a solid state drive that is completely silent, you will want to set up a monitor in your studio and run cables through your wall to a computer outside the room. You can use a wireless keyboard and mouse to control your recording software. This also cuts down on the heat of your studio.
Voice actors get paid on a per project or per job basis. Your earnings as a voice actor range from: $35 for a small market radio spot, $150 for a 15 second recording for say a small website, $250 – $350 for a 30 second major market radio commercial (Plus use fees) to about $2000 – $5000 per audiobook, as an established voice talent. There are several ways to calculate how much voice actors get paid, with the most common being the word count of the script. The use of the material is also taken into consideration and whether or not you are granting a license to use your material for a specific duration on specific channels or if you are seeking a fee for a universal buyout.

When you come to actually recording your voice, try to think of the mic as the ear of your listener. Picture your listener, have an opinion, and read the script as if the words were coming to mind that instant. The distance between your mouth and the mic should be about the same as the distance between your thumb and pinkie when making a hang‑five gesture (see the picture above). Move closer to the mic when you lower your voice and back off when you speak louder. On‑line dictionaries such as the Merriam‑Webster one pictured here, often include audio examples which can help you clarify pronunciation. Just make sure that you use an American English or UK English (or other language!) version as appropriate. (Remember, while you have your engineer hat on, to take account of this when setting levels.) Always use a pop shield, and I'd suggest trying to work slightly off‑axis, as talking to a point just to the right or left of the mic will prevent bursts of air and drops of saliva ruining your recording. I'd also recommend wearing headphones over one ear only, as this allows you to judge volume and listen for clipping and plosives on the recording, while also hearing your natural voice, which makes it easier to focus on that message we talked about. Simone demonstrates this technique in the picture on the next page. Hhe's working slightly off‑axis and has backed off an inch or two to deliver with more energy.Typically, you'd record with your mouth approximately the distance between your thumb and little finger from the mic, as pictured here.

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.
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.
