Making your recorded voice sound better is a tricky problem but not unresolvable.
Improvement depends on what the issue is to begin with.
First, if your voice is too high pitched, working to increase your vocal range is important. Practice breathing and speaking from your diaphragm and not trapping the sound in your throat may solve the problem if it's not an acute nasality.
Second, if your voice is too nasal, there's a two step solution. Exaggerate the sound, speaking with as much nasality as possible. Then, once you've established that you have identified the locus of the sound, ie in your nasal and sinus passages, begin to breathe deeply and imagine the sound coming first from your mouth, then from your throat, then down through your torso to your stomach and then coursing through to your diaphragm.
Third, if your recorded voice is blurry, it may be an issue of "mush mouth" that is, you may not be hitting your dental (t and d) and plosive (p) ) consonants sufficiently. There are a number of exercises online to improve your use of consonants. A good coach will help you to identify where the issues are and provide exercises to help you.
Fourth, if your recorded voice is a monotone, reading the news or the phone book, supplying variation just for the fun of it, is good practice. Listening to good newscasters and actors and mimicking them can also help. On occasion, I've had clients sing their speeches and presentations just to get away from being "one-notes".
