Is it possible to get a softer voice and how?

Softer Speaking

Yes, you can develop a softer voice by simply using more air when you speak. Generally speaking, most American English speakers use very little air, giving the vocal tone an edge that sounds flat to the ear. Smoking, over time, can further effect the tissue of the vocal chords increasing this edgy sound. When practicing using more air, do not overdo. Just a little breathy-ness will go a long way in softening your sound.
