First of all, don’t be put off by the word technical. The ‘technical’ skills you need to learn to involve how you record and then edit your recording and of course you will need a home studio to do this. This needn’t be a daunting prospect though. Many freelance sound engineers are available who can help you with this – contact us if you want a reputable one.
Your own voice is your most important piece of equipment. If you're new to the voice-acting world, look around to see if there are classes or coaching in your area. Outside of class, practice speaking clearly and confidently. Learn to do this even with material you've never seen before. It's also important to learn voice care – straining or injuring your voice can hurt you and your career.
"The editing process for all our titles starts with receiving the Pro Tools sessions or WAV files and the engineer's script, which has the markings of how many takes there were, and which ones the director liked best. In some cases, I use Strip Silence and add a bed of room tone to expedite the assembly edit. In others I'll add the room tone as I move through the audio. Once I had all the final takes to be used in [Favorite African Folk Tales], I went back to do a fine‑edit pass and created notes on any issues, such as misreads, mispronunciations, noises, and so on. With that list, I was able to discuss with Alfre how we would address the issues. Since the actors' schedules did not permit them to come back in to do pick‑ups I had to do some creative editing.”
As the engineer, your key job is to select and set up the recording space, choose and position the microphone, set levels and make sure you're recording a good, clean signal at a healthy level. Like music, the louder the signal you want to record, the less audible the noise floor, but you don't want to have to speak louder than sounds natural, and you don't want to overcook things when tracking: any distortion will be very noticeable on an exposed voice part, and an otherwise great take with digital clipping won't be acceptable. If you notice clipping only when you start editing, software clip restoration tools might help to make the take usable, but it's not going to be perfect. Remember that although you may have needed to record 'hot' on analogue tape and older 16‑bit digital recording systems, modern 24‑bit A‑D converters can accommodate a much wider dynamic range, so you no longer have to track so loud: you can leave much more headroom.
The quality of your voice over depends almost entirely o the skill of the voice actor you use. A good voice actor will have perfect enunciation (ie, be very easy to understand), speak at an ideal pace (not too fast and not too slow), and have a pleasing voice. They should also be good at acting, and able to convey the feeling or emotions required by the script, using vocal variance and tone to keep the words interesting while also embodying the desired mood.
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.
First, since you’ve decided to use professional talent rather than record your own voice over, you know the challenge is to find a person whose interpretation of your script and voice quality represents your brand. You might have a list of qualities — female or male, a mature or childlike voice, a certain accent, authoritative, and so on. This is your voice profile. It’s best to start with this list already defined so you can easily narrow your results.
"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.”
