Like pacing, vocal tone and inflection refer to ensuring you speak in a natural and pleasant manner. You want to be friendly and engaging, but not so much that you sound fake. No one wants to sound like a game show host. But, you also want to avoid monotone robot voice which, like pacing that’s too slow, can be boring and off-putting for listeners.
1. You need to get oriented with the industry. You need an education in this business prior to investing in it—especially if you hope to be valuable as a voiceover talent. You need to understand who your core clients would be and who you would eventually create a voiceover demo for, namely, producers. If you’re not servicing them, then you’re not servicing your self. This is precisely why I wrote, “The SOUND ADVICE Encyclopedia of Voiceover & The Business of Being a Working Talent.” You need insight as to what’s needed and wanted of you in this field, and how professional sessions are run, otherwise you’ll likely frustrate yourself with unrealistic expectations.
It's only after this sort of processing that I'll start cleaning up the recording and dealing with the gaps of silence between spoken passages. A noise gate (or an off‑line 'strip‑silence' function) can be used to automatically mute sections that fall below a certain level. However, if not used carefully, these tools will clip the 'T's and 'P's off the ends of words, and shut out natural breathing sounds. Worse, if your recording is noisy, a noise gate will actually draw attention to the problem, since your client will be able to hear the difference between room tone and absolute muting. Another trick is to use a downward expander to reduce the noise floor of quiet sections, rather than cut out the noise completely.
"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.”

Before you do anything though, ask yourself why you want to become a voice actor. If you know upfront what your goals, expectations, and motivations are, you will be more successful. Setting small achievable goals and placing deadlines on them will make sure you stay on track, even if you only want to do voice over as a hobby instead of a full-time career.

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.
This guide is designed to give you an insight into this hidden world and provide you with enough information to help you make an informed choice on whether or not this is a potential career for you. If you already are a voice actor, we will be giving you some tips and ideas to help you improve your voice acting skills to help you experience a dramatic difference in how you approach the written word.

A demo recording of you doing voice-over work is your CV and your business card combined. If you're applying for a voice-over job, you can send the potential customer your demo via the Internet. Ideally you have multiple demos for different types of gigs. For commercials, clients want to hear 60 to 90 seconds of voice work. If you're auditioning as an audiobook reader, five minutes of demo proves that you can stay in character over a longer stretch of time.
