Hi,
You may be speaking from your throat rather than the front of your mouth It is very hard to get volume and projection from your throat.
In fact you'll give yourself a
sore throat very quickly if you make a habit of it.
The more you need to project, the more the voice needs to come from the front.
Consciously learn to generate the sound from the front of your mouth. You can practice simple vocal exercises in your home or car for this.
One is to just say eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee in a low-medium voice and watch where you feel the vibrations and move the effort to the front (hard to describe, but you'll get what I mean when you try it).
You can have a few sessions with a voice therapist who will teach you basics and help you to have a control a.
It will ease you to for public speaking). Get some voice lessons and keep your moral high.
Besides the one above, some of the other basic exercises
saying e ee eee eee eeee with rising pitch and repeat with the other basic vowel sounds ooo and aaa.
To practice your vocal range, place a stirring straw between your lips and start to make a low “oo” sound.
Slowly start to increase the pitch of the “oo” sound. Focus on extended, continuous sound at low-medium volumes, not shouting or whispering.
The key is to stabilize your voice in front rather than volume/projection. Once you get the front-stability, it will be easy to ramp up the volume/projection.
Hope I have answered your query. Let me know if I can assist you further.
Take care
