I’ve seen people talk about this vowel thing but never understood what it means. So I don’t know what is meant by making an AAAH sound while playing the saxophone. But if it works for you and improves your playing that’s a good thing. But beware there is a lot of saxophone teaching mumbo jumbo out there.I've noticed than when I make the genrally suggested “AAAH” sound as if I'm singing it, my tongue sits down low in my mouth. For me this produces more of an AARGH almost guttural sound and I can feel tension in my throat and hear it in the pinched tone.
For me lowering the tongue seems to reduce the flow of air. When my tongue is relaxed in a more natural and slightly higher position and I think 'OOOO', the sound is smoother and fuller. If I raise the back of my tongue higher I get more of a EEE sound.
