The main question I get all the time is how does one break into voiceovers. Here are some thoughts about different ways that might work.
For starters, its' not a candy store thats locked at night so breaking in is maybe not the image you want.
There are many points of entry. On hold messaging for small companies is a simple way to start. You can do audio books for ACX (Audible.com) and hope they sell so you get your percentage. The experience of doing an audio book will hone your skills and then you can tell voiceover talent agencies that you have done a couple of audio books. You have to create a few projects because no one wants to go first when it comes to hiring.
HR departments use an endless stream or narrations explaining company policies. This can be for powerpoint presentations, videos or just audio.
There are media production companies that make their entire living just creating presentations that all have voiceovers.
You must have a really great voiceover demo that you can submit to people to keep in their files so when they need narrations they have examples of your work.
You will find a way to get work if your skills are professional, and you set out to explore. Keep in mind that no one will come to "Discover you" You have to prepare your skills and then take yourself into the market place and you will find work if you make the commitments needed.
