Speaking the language is the first step to fitting in anywhere. When visiting a foreign country, or even beginning computer programming, there is a basic set of terms and tools you need to learn. It is the same when becoming a voice actor. Learning what a noise gate, a compressor, or a sound card are, can make the difference between struggle and success.
The platform that you produce your work through will most often have explanations about the features and plugins that you can use. I use Reaper, and their website has an entire series of videos about what the program can do, and how to use the features. Any internet search will yield countless videos of other producers showing how to achieve a certain effect with the different programs. Some people have even posted tutorials on how to add your own plugins to achieve the perfect audiobook sound. BrokeMC on YouTube was one of my favorite resources when I first started out.
Part of the struggle in beginning to voice act is the sheer volume of content. It can be intimidating, and difficult to know where to start. My advice would be to pick an editing software and learn everything about it. Find multiple sources on how to use it, either through articles or videos. Pick your favorite children’s book, record a few minutes, and take the time to click every button. Familiarize yourself with the different effects and what they do. This will make it much easier to create a final product that fits into the client’s requirements from the beginning, instead of having to make too many corrections after the fact. When I talk about “speaking the language,” it boils down to being familiar with your tools, to create a better product. It can be as that!
