As you see, you can use your own voice or someone else’s professional voice for your promotional video or business venture. There are so many little aspects you need to consider. You do these correctly and it will sound so much better and your message will go through very clearly. If you do it incorrectly, the mistake(s) will stand out as well. So, use voice to your own advantage, put emotion into it, use your own accent, use raw emotion, be yourself, match your voice to the market, and above all, just have fun. Your promotional piece should be fun and it should be inviting. As long as your message gets delivered, it’s what’s important.
