Do you have a great voice? Maybe you're not the world's best singer, but you might still have a good speaking voice. Couple that with a home studio, and you could consider a sideline as a self-producing voiceover artist. Making money as a voiceover artist used to mean living in a big city, mailing out demos, and sitting in traffic in between auditions. As with the music industry, though, affordable recording gear, home studios and broadband Internet have reshaped the job. A work‑at‑home mummom in Manchester can record a phone greeting for a travel agency in Rome; an actor in New York can narrate a video for a tyre company in Russia; or, to offer my own example, an American ex‑pat can record for an ESL (English as a Second Language) textbook, while his Brazilian wife lends her voice to software being developed in the Czech Republic, and all from the comfort of our house in São Paulo.
"When recording voiceovers at home, you have to focus on performance: keep your energy levels up, stay true to the page, pronounce words correctly and consistently, and make sure you keep to a schedule to make the deadline. Prep well so you don't waste time second‑guessing yourself, looking up words as you go, and remember to not over‑ or under‑direct yourself. Also, make sure you know your recording equipment and room well; being able to quickly make adjustments to mic placement, levels, and so on, will make you more efficient.”
Congratulations! You should now have a finished voiceover recording. Save a final copy with the extension _master and use this version to save another copy in the format requested by the client. But don't think your job is done when you hand everything back to your producer‑self. Running a profitable home‑based voiceover business takes more than building and equipping a home studio and recording and editing audio files. You still have to design a web site, launch a marketing campaign, and secure new clients — all of which is something we'll look at another time.  
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.
