Playing with Tone

I was listening to Radio Lab, on musical language theory and I was brought back to the reason why most people will go “Huh?” when I say a simple word. Apparently most people hear words by the tone instead of he actual word. Which is the main reason that people don't understand me. I am trying to think how to warn people in advance. My problem on the phone, is when I attempt to warn them in advance they often hang up. I almost need a normal person to record a warning for to play on the phone first before I speak. I am not tone deaf, but the area in my brain that transfers the actual word on one side and moves to convert to tone is damaged. Also because I lost all feeling in the mouth area, and tongue, I am unable to teach the tongue with the brain how to perfect my speech. I listen to my speech, and self-correct by repeating it. I tried to delay speech with an appliance during my speech therapy to slow me down and it worked some. But my problem with slowing down spontaneous speech is that I forget my thoughts. I can do it while reading something that is easy. You know the old joke about walking and chewing gum? Well, that is me, now. I cannot walk and talk to people, and even friends get bothered when I stop them to say what I want to say. All these things we take for granted in life, now for me become a challenge. I wish I could somehow breakdown each problem and let them experience it for a second in order to get their understanding.
