Teaching projection to anyone is similar - if not directly related to how singers are taught to sing and/or control/use their natural lung capacity and so forth for purposes of being heard - i.e. volume...although it is NOT just lung capacity but much more.
It's a learned technique that once learned can be controlled by the individual. Having had 16 years of private vocal instruction I can tell you it's NOT an overnight process. Basically it's a matter of them understanding the physical parts of how proper breathing is accomplished and using that in combination with proper diction to accomplish the projection of the voice enough to be heard in a relatively large auditorium. HOWEVER and I am going to qualify it here - I would NOT expect ANYONE (and much unlike MY big mouth) to NOT overdo what cannot be done - or that is that can only be done with amplification. It depends upon the acoustics of the building you're in. I have worked in about a 130 seat theater for a long time and being heard in there is rarely a problem. BUT I've also done shows at the Opera House here with full orchestra - THOUGH STILL was heard in the third balconey because the acoustics were so incredibly good and I didn't need to "push it". Fact of the matter is - that is what MOST people think you MUST do to be heard and therefore experience hoarseness, sore throats, and in many cases loss of the voice completely - or at worst early vocal death (thanks to Musical Theater - and untrained actors).
Basically put, it's an element of understanding the physiology of how sound is produced by the human voice and how the volume is controlled through properly taught breathing techniques. Again, NOT an overnight process. If they understand what the diaphragm is and how it operates in the body, and if they understand the vocal cord structure and how both that and the diaphragm, lungs and diction/placement of tone/sound is produced - then perhaps they can understand how to develop a more voluminous sound without hurting themselves vocally. I have been able to teach that because I've taught voice to singers but if I were NOT qualified, I'd not attempt to do that and thus feel responsible if they damaged their voices by improper techniques. It IS VERY similar to teaching singers how to sing and/or produce tones using the whole body - not just those elements of the anatomy that combine to make sounds at whatever volumes they will be made.....all without hurting someone vocally.
Perhaps you can find a vocal instructor to come in for a session and explain the techniques of proper vocal sound production and all the elements involved so they can get an understanding and a feel for how to adjust as required for the space they're trying to fill. IF the place is too large and the acoustics are weak, then amplification should be the order of the day - general, ambient miking would be required.
I could go on but this is too long already. I think you get the idea.
