Volume is one issue, but don't forget about clarity. A short, clear message is much easier to hear and understand than a long, complex, or possibly ambiguous message.
Volume is about how much air you can push past your vocal chords and how efficiently you can use your vocal chords. You are best off taking advantage of your natural range. Many people try to force the sound of their voice either too high or too low. Either will hurt your volume and strain your voice unnecessarily. Remember the vocal chords are muscles and must be trained. A wide open throat and full lung capacity will result in the best volume, and don't forget to breath from your diaphragm. Correct enunciation and a clear concise message are equally important.
Also, if you describe yourself as soft-spoken, there could be an issue of self-consciousness as well. Just let loose and relax your lungs and throat. Push the sound out from your abdomen (diaphragm).
Search for voice or singing training/coaching tips for more information. I learned the hard way; in the Marine Corps, but it worked very well.
