How to do do voiceovers
Talking is the most natural thing in the world, but recording yourself without the benefit of facial expressions or body language can be a bit unnatural. To make your voice overs sound clear and intelligible, focus on volume and projection. Also, consider the pacing of your narration. Aim for a pace that is neither too fast (which can cause the words to slur together), nor too slow, which might put your audience to sleep.
It is important to warm up the voice before recording. A good way to do this is by reading the script aloud, which can help find the right balance of volume, projection, and pacing.
When preparing to record, it’s helpful to have a pencil and eraser nearby to make marks when necessary. This can be used to indicate pauses, when it’s appropriate to lower or raise the tone of voice for emphasis, and even where to stutter for effect.
It’s also helpful to have a video monitor in front of you to watch as you read and record the voice over. This will help you keep the pace of your narration synchronized with that of the video. Also, if you have trouble matching the tempo of the video to your recorded voice, it’s okay to leave some silence at the beginning and end of your recording to give the audio editor time to trim it for a better fit.
