I noticed that I wasn't pronouncing my words properly when I talked. I'd sometimes chew up my words and speak too quickly, which would kill the smoothness of the conversation. So I started reading out loud news articles and anything that I could get my hands on with a pen in my mouth. I bite down on a pen across my teeth and then try and talk with the pen as an obstacle in my mouth.

This forces my tongue to work harder and it makes be think a lot more about my pronunciation as a I talk. Practicing for a half hour a day has helped my talk so much better. Also, the talking warms your vocal cords, so when you go out and talk to women, you're voice is nice and projected because you've spent time already warming up.

Final tip. Try keeping your tongue at the base of your mouth behind your bottom teeth. This allows more air out and gives your voice an extra bit of boom.
