"Make it conversational"

 I often see producers wanting a conversational tone in the voice over. One part of that is lowering the volume of your voice. Don't shout at the microphone! It's designed to amplify your voice.

And remember, we speak in phrases. Usually, somewhat deliberately, as we think about how to express our thoughts. When reading copy that calls for a conversational delivery, don't go racing through it without pauses. A road runner approach doesn't work for conversational.

I do a lot of educational and training narrations. Using a conversational delivery is spot on. 

Here is a link to an online tutorial I voiced having to do with publishing and plagiarism. 

Slower is better for on hold messages

So no joke,over the years I have voiced hundreds and hundreds of on hold messages. It's a different style of read. Go a bit slower with your pace so the caller can take in all the information. When you are recording the on hold script and come upon the company's phone number, hours of operation, and address, slow it down. You don't want to go too fast in these sections. All in all, it's a slower voice over than say a TV commercial or radio spot where things move fast .
Remember, when recording on hold messages, slower is better!
