"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.”
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.
Perhaps you come from a corporate business background, but you have a remarkable capacity for accents and original character voices, or you’ve been in radio and broadcasting for a number of years.

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.
However, there are lots of second tier voice over agencies and ones that are just getting established. One of your goals as a voice actor should be to get listed by an agency. However, wait until you have at least established yourself and put together a portfolio of work and super hot demos you can send out to them for consideration. When selecting an agent you need to carefully examine who they currently represent and then ask yourself: How do I fit in here? Does this agent have anyone like me on their books? If not, you will most definitely stand a better chance of being represented.
