I have a hard time proof reading my own copy. Sure the spell checker
helps with repeated and misspelled words but not with left out words,
wrong tense, words in the wrong order, etc. Some will be caught by
a grammer checker but I don't like to use them because of all the false
I also don't always have someone available to proofread for me especially on short notice.
But now I can using this:
Free text to speech software with Naturally Sounding Voices -- Free NaturalReader
It's a text-to-speech reader (free version) that you can download. You
just copy and paste your text into it and listen. It's amazing how much
easier it is to pick out mistakes.
Give it a try.
