Recently I've been trying to perfect my speech so that I articulate and enunciate everything correctly. Today I was trying to say "that's the thing" in normal speech speed, and the "the" doesn't get enunciated properly at all. It sounds sort of like this: "that'sa thing". There's not enough time for my tongue to go from the roof of my mouth pronouncing the "s" in "that's" to under my top front teeth to get the "the" pronunciation without slowing down my speech strangely. Is this just a problem with me? I've noticed that when I pronounce "s" the air is always going out of my mouth from the right side of my 2 front teeth. If I try to make the "s" sound come out from the left side of my 2 front teeth, it sounds strange. Maybe it's because I've been doing it like that my whole life? Here's another one. Try saying "I received the package this morning" in a normal talking speed. Do you notice a bit of trouble going from "package" to "this"? There's a delay between the two words as my tongue has to go from the middle of the roof of my mouth to sort of make a plucking motion on the top of my teeth to create the "th" sound for "this". It doesn't flow like a lot of words are able to. And if I try to just go through it, saying it like I'm casually talking without any real care if I pronounce the words the correct way, it sort of turns into "I received the package zis morning". That's the only way to make it flow at the speed of my speech. I got into theater a year ago and that caused me to pay close attention to how I'm speaking, and I discovered a lot of little nuances about speech that are never talked about. I'm wondering if everyone goes through this, or is it somehow exclusively a problem with me and my way of speaking, or possibly the structure of my teeth? I don't know.
