It's not just about setting up your session, hitting record and the laying down some voiceover tracks.
Whichever mic you use, try recording at different distances and at slightly different volumes with your voice. Do many different takes where you speak louder and then slightly softer, while you vary the distance. Take a good tour to keep refining which sounds you like better. The interaction between the electronics in a mic and a specific voice involve many variables, so you have to experiment to discover the many different sweet spots for the various tones of voice you might want to use. When you speak softer and closer to the mic it's obviously more intimate AND there is more saturation in the sound that is recorded. Speaking softer and then using more "Head Room" in your spoken tone will give yet again a different effect. The important thing is to become very familiar with your own recording set up and how to best present the sonic identity of your voice based on each job.
