This is refreshing -- a statement of purpose that deals, immediately and in detail, with the author's actual purpose. Good job. Your style could use some tightening, though, but I'll leave that for our contributors who enjoy going sentence by sentence. I would advise, you, though, not to open by highlighting a weakness in your application:
This is the only program I am applying to as I feel it is the best fit for someone like me who does not have extensive clinical background in speech language therapy or audiology.
Really, why point out what you lack when you can use the room to talk about all the skills and training you have, instead?
