Raising your voice!

Ok...so I struggle with this a bit. It seems like it is the only way to get Jack to "hear" me. Its unfortunate. I do not want to raise my voice...I don't want to be "that" Mom. But how do I get Jack to listen?
Example..."No Jack please leave Kita's bowls"...distract...take him into next room and give him a toy...play for a second with him. Cool..it worked...go back to trying to make breakfast/lunch/dinner whatever. But..no there goes Jack back to the bowls...this time to drop the toy into it. Again..."no Jack please don't touch..bad" still in a super calm but firm voice. Jack throws a fit...and sometimes attempts to hit me in the face.
Stay calm...walk him over to the toy area...good boy...play with your toys. Nope...there he goes back to the bowls...so I lift them up...place them on the counter...say in loud voice....NO Jack...bad!
So we have accomplished nothing except that...I have now shouted at him...and removed the one item that HAS to stay on the floor in order to get him NOT to touch it. And this has been happening since he could crawl over to the bowls. So as you can imagine..by the third time to the bowl....my voice is fairly loud and super firm. Therefore most times we just simply remove the bowls every time Jack is awake and downstairs. Not fair to Kita...and not really teaching him boundaries.

I do not want to shout at him...I do not want him to A. think that it is OK to talk to someone like this. and B. think that this is how to get your POINT across to the other person.
I am going to make a SUPER CONSCIOUS effort to stop this. Now that Jack is "talking" I notice that he kind of does so in this loud..sort of shouting voice. He spits out these short one syllable very loud "words" we will call them. Perhaps this is how he thinks that you will "be heard"..because when Mommy really wants me to "hear" her she shouts at me. Yikes...is it too late to correct this. I hope not! After all its not like this happens all the time.
