To begin a career in voice work for visual novels, first, practice a lot on your own. Experiment with different voices, accents, and emotions. Next, look for small, independent visual novel projects that are often more open to new voice actors. Offer your services for free or at a low cost to gain experience. Build an online presence, like a website or a YouTube channel, where you can display your work. As you gain more experience, you can start approaching larger visual novel companies.
Start by taking voice acting classes. This helps you learn the basics of voice control, projection, and acting. Then, create a demo reel that showcases your different voices and acting abilities. You can also network with people in the visual novel industry, like developers and producers, through social media or industry events.
One way to start is to study the existing voice work in popular visual novels. Analyze how the voice actors perform, what makes their voices suitable for the characters. Then, you need to invest in some basic recording equipment to practice at home. After that, join online voice acting communities. There, you can get feedback on your work, learn from others, and find out about potential job openings in the visual novel field. Don't be afraid to start small and keep improving your skills over time.
