Working on videos of a presentation mage by a speaker.  

Most speakers will speck louder, and softer. 

Is there a way to lower loud vocal, boost softer vocal so a more consistent vocal track.

Thanks 

This is what you want to do, whether you can might depend on the exact version of Studio you are using:

Try the Leveler effect

Open the clip in the effects editor, switch to audio effects (click the music-note at top-left) and select Effects -> Leveler)

There are some presets, you can also adjust the controls to suit the loudness of the quieter vocals. There's an old (quite useful) forum thread here that has some information about using the Leveler effect and what the controls do.

Unfortunately, this feature is not a normalizer. It applies a uniform -12dB gain, regardless of the audio level of the clip.

A normalizer should never apply a negative gain, unless the target is set under 0 dB.
