"do you want to talk to me on the phone to hear my voice? to see how bad it sounds if so send me a message to my inbox and i will give you my phone number"
That may not be necessary. You answered all my questions plainly, which gives me a much greater idea of what your problem might be.
Inconsistent range/sound?
YES
Inconsistency in the voice is either temporary, or long-term. Your answers to my other questions suggest that you have a long-term problem. For long-term inconsistency problems, that means that the vocal structures are improperly formed. Either they are being formed currently (meaning you are probably below the age of 27) or your throat wasn't developed properly to begin with.
If you have trouble keeping a proper register when talking or singing, it means your vocal structure is malformed. If your voice is currently breaking when you talk (like a young boy in puberty) it means that your body is currently trying to form the vocal structures.
Do you have speech impediments or problems forming phonetics?
YES
Problems with speaking could be caused by the aforementioned problems, or from problems with muscle control or nervous function. If you don't have any known nervous or muscular disorders, speech impediment is likely to be an anatomical problem.
Vibrations/oscillations?
YES
If the voice sounds funny, it may mean that the wrong materials were used in constructing it. If the diet is very poor during early years of development, the body will use whatever is on hand to construct itself, rather than what it is supposed to use.
Unfortunately, the only quick fix to this type of problem is a trachea shave, which is not advised. It is dangerous and could end up leaving you sounding worse.
If you practice using your voice a lot, you can correct this type of problem over time. But we are talking about a potentially long time. Most likely, it will take years of practice and controlled diet to get your voice sounding like it is supposed to.
Raspy voice?
YES
Raspy sound is probably caused by a combination of the aforementioned factors.
My best recommendation is to eat a light diet and to practice using your voice, a lot. Preferably, somewhere in which people won't get annoyed at your horrible singing. Persistence is key. It may take months before you hear a signficant improvement in sound, but it can happen.
As far as how to sing/talk, it's something you just have to know how to do. Once you know how to do it, you can practice it to change the voice. It is very frustrating in the beginning.
The human vocalization system is much like any other part of the body. If you train it enough, it will get better. The speed at which it gets better depends on how intense you train it, what your state of mind is, and what your diet is like. Remember, the human voice is a muscle, it's just more complicated than your biceps.
Knowledge helps. Study things like linquistics, and listen to really good singers. Listen to what they are doing with their voice, and see if you can determine how they did it. The more you know about what you can do with your voice, the more capable you will be to change it.
