We can guess at it, but there’s nothing quite like hearing an actual voice presentation.
Don’t do anything to it. Just shoot it, cut it to length, export it, and post it.
Do you have a nice quiet, echo-free room? We can’t take echoes and bare-room, wooden-floor sound out of a voice track. No effects and filters for that.
There is an explainer video series by a presenter who got the video exactly right. Good color, sharp, clear, excellent lighting, and terrific chroma-key backgrounds. When he starts talking he turns into a kid recording in a bathroom. You probably don’t want to sound like that.
The two desperation methods for conjuring a studio from nothing are an overstuffed garage and a Toyota.
Also see the Kitchen Table Sound Studio.
