I'm going to take a different view, one that has come up in several other threads on this type of topic before. You are writing phonetic dialect. If your story was filled with dialogue like you've written in your original post, I'd put the book back on the shelf and move on. This kind of writing makes reading tedious, and I want to read stories that allow me to dive in and that carry me away. But I don't want to have to work for it--it takes the pleasure away from it all. I don't mind working a little to flesh out the theme or plot of a story, but I don't want to have to work hard to just figure out what words are being used, aside from an occasional peek in the dictionary. At least in this latter case, I learn a new word.
Point number one. In dialogue, write words not sounds. (There are some exceptions, but not many, and not that carry throughout a story in bulk.)
Point number two. If you (1) throw apostrophes all over the place in the dialogue, (2) leave out vowels in word after word, (3) spell real words wrong, and/or you substitute consonants in real words so the word is the same but just sounds different in how it is pronounced--just to make the speech "sound" like you want--give it up immediately. The reader is going to go crosseyed and it really doesn't add anything to the story if it is done over and over again.
Point number three. Sure, you can find authors who have done all kinds of unconventional things, but look at those authors. They usually are skilled and experienced authors who have the savvy to pull it off. This kind of thing is extremely difficult to pull off, and even if done well, it will piss off some readers. For a beginning writer, writing phonetic dialogue will likely land the story in the slush pile, thrown not placed.
Point number four. Some new authors do this because they think it is cool and original (not saying you, the OP, are of this mindset). This means the writer is using this "technique" for the author, not for the reader. This writing business is all about the reader, not about the writer. We do things for the reader, not to make ourselves look cool or original. One way to thrill readers is to do something original, but we should never make those readers have to work hard to see the originality in the stories. This is where writing talent really comes into play. A talented writer knows just how much of this kind of thing is needed to get the story-points across the reader. Those authors who have pulled this kind of thing off probably were able to do it because of their writing talent.
Point number five. NEVER choose an unusual writing technique solely because this published writer or that published writer has done it before. ALWAYS choose that unusual writing technique because it best serves the story--it is the single best way to tell this story.
That said, there are ways to get unique or unusual speech patterns into a story without pissing off, or turning off the readers, or making them break a sweat getting through the passages of dialogue. Putting in unusual word usages is the best way, but with some economy of use--don't put them all over the place. A character may have some pet phrases that can be used, and he/she can "invent" words, but in these cases they should still resemble real words (as opposed to leaving out vowels or otherwise spelling the words wrong). He/she can also combine two words into one on occasion, with some unusual or region-specific meaning or flavor. It doesn't take much of this to establish that the character has an unusual dialect or an unusual method of speaking. And this is all a writer has to do--establish in the reader's mind that this character has an unsual manner of speaking. If doesn't have to be cooked into the reader's head with a book full of dialogue that is gravyslathered with apostrophes and starved of vowels.
Also, keep in mind that this type of phonetic dialogue frequently gives the distinct impression that the character is both stupid and uneducated (exceptions are when they are used strictly for accents that are "foreign" to the reader). The latter is not that big of a deal, but do you really want your readers to have the impression that all of these characters are stupid? You, as a writer, will have to work mighty hard to show the reader that they are not really stupid, but just have unusual speech mannerisms.
