My grandma says I have a beautiful voice, can you teach me the trade?

A beautiful voice is a nice start. But understanding how a text is structured, what the writer wants to convey, and how to present it to the listener in the best way possible—that’s the essence of the voice acting profession. Of course, you also need to invest in an acoustically suitable space, equipment, and the knowledge and skills to use these things. If you think all that fits you, then a voice acting course could be a big step in the right direction.
