In other words, Mirek gave us all the information we needed to start the job. Unfortunately, though, that's not how it usually works! Usually, you'll need to work hard to get all the information you need from your client to do the job well. If you're at all uncertain about their expectations, whether about the performance, or about technical and organisational issues such as file formats or payment procedures, save yourself time and a headache by clearing up all doubts beforehand, and don't hit the record button until your client has given you the green light by email. With that sorted, you can more easily don your other hats and get on with the job.

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.

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.
3. You need a simple, reliable, home-recording setup. Keep in mind: Your objective is on being the best voice talent you can be, not the best production studio or recording engineer. Nevertheless, you do need the ability to record, edit, and turnaround a proper audition. Do not run out and purchase a mic! You can’t return it, for hygienic reasons. Besides, there’s a bit of a learning curve to this and recent industry advances have made having a home “studio” easier and more affordable than ever before. You could have the best gear and the coolest toys on the block, but if you can’t use them it’s a waste. (Tip: What you’re recording on matters less than where you’re recording. Find a quiet place like a closet full of clothes to record in.)
First, I like to listen to the entire voice over recording from start to finish. I may make notes here and there to remind myself of something I want to go back and edit, but this time through I really just want to concentrate on the overall pacing and tone of the recording. Does it sound like I hoped? Did I rush or speak too slowly? Did I flub any words, mumble, or misspeak? Are there weird silences or unknown sounds?
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.
