hi Raymond,
I think i know what the problem is. There are a few things that could be wrong. first of all you've got to determine whether you are using your vocal muscle properly or whether you are trying to blow air through slack vocal cords. The vocal muscle is located at the back of your tongue. Before i explain how to make sure you are using it properly. I'd just like to say that the consequence of not using it properly or at all is vocal fatigue and eventually nodules or a whole load of other troubles too many to mention. So it would be good to check with an ent specialist at a hospital to make sure you haven't already done dammage. if you have then you'll have to rest abit and then correct your vocal action immediately.
To correct it quickly i would use the word GooD to train yourself to speak properly with your tongue. The G part of the word should be started at the back of the tongue and the D part of the word should explode out of the tip. If you keep repeating this word, quietly at first and then get louder, making sure you feel the two different impact point which are the G at the back and the D at the front of your tongue, then you'll be in no time celebrating with the ability to use your tongue properly in a way that will aid your speech and singing.
The reason this is my advice to you is because the tongue muscle is the most important thing to control in speech or song, to the degree, that if you master it, you won't have to worry about breathing or anything else that is often taught by some voice coaches. Learning to control your tongue and making it strong enough to do it's job, is all you need to do. simple really.
Have you heard about the problems with the root of peoples tongues tightening to much and messing up their singing voice? well if you have this simply proves how important that part of the tongue is to control. a muscle only over tightens when it is too weak or badly controlled. so by strengthening and controling it well, it will not tighten too much and your vocal cords will be able to get the tension they need to change pitch as well as maintain pitch. If you imagine a guitar being played, and while it's being played someone was loosening the strings, eventually you'd have no sound or very poor sound at least. So just as the quitar strings have to be held at a specific tension, so do the vocal cords. And that tensioning is done by the back of the tongue muscle, which is called the hyo glossus. I know i've gone on abit, but i am talking from my own experience, and from years of testing and i sing for a living, and quite well people say, lol!!
