While voiceover coaching is imperative to having a chance to succeed in the voiceover business, it's also a good idea to take advantage of what you already have on your phone! Use the voice memo app and practice recording scripts. Read them and then listen back. Does the performance sound convincing and persuasive? Is the delivery similar to what you hear in radio or television commercials? If you have zero experience, the answer is likely no but this is a good way to get started!
