Unless you are experienced, it can be daunting to know what to say to the voiceover artist. Don’t worry, I am very flexible and never feel you can't comment. I will help YOU help ME deliver the best performance for your script. A few basic tips to help with the directing would be to confirm who the target audience is and the tone of the script (for ex. aspirational, confident, serious). Try not to give too many directions at once. I’d say 1 to 2 maximum before each take, so that the voiceover artist knows what to focus on & try differently each time. My job is to give you choices anyway, and I always make sure I have understood your directions. There are some exceptions, but a golden rule in this industry when directing a voiceover session, is to avoid what we call the parrot style method. It means not directing by reading out the lines yourself in the way you want them read out by the voiceover artist. It’s more productive to give specific words for direction for ex. ‘more authoritative on this paragraph, less urgency on this line, a slower delivery for the opening line etc.
