To sit; or, not to sit- that is the question. Whether it is noble for one to sit or stand during a voice-over session depends on the project you're recording; and thus has been the subject of on-going chatter in the voice-over social media platforms. Most would agree that standing is the best; but if you consider the nature of the recording (the subject matter), and/or the length of time you'll be at the mic or how long the project is, some say sitting would serve best.
Standing at the microphone has its advantages...
...and some disadvantages:
Sitting at the mic has some advantages too:
Keep in mind that when I refer to 'sitting' at the mic, I don't mean in a chair (like in the graphic to the right). I'm referring to a bar-stool type of seat where you can have your knees slightly bent (as opposed to parallel to the floor).
Try doing a video search for 'voice-over recording session'; you'll see that most of the videos show the person standing while recording. Use your common sense, if the script is energetic and/or emotional your best option would be to stand; whereas, non-dramatic or (dare I say) boring scripts you could sit down, because they typically don't require much emotion or energy.
For the most part when I record voice-overs, I stand; however, I sometimes let the script decide (barring any direction I've gotten) as to whether I sit or stand at the microphone.
Your results may vary.
