Misspellings, sentence formation matters—-this is how we defeat the algorithm; it does not have "common sense" which helps us to understand and successfully complete words in Captcha? We can use varying misspellings and another human can use common sense to figure it out but the algorithm looks for consistent patterns or the censors can add them to word lists but if we vary mistakes and structure the algorithm formula cannot take it all into account without making endless other mistakes that humans would not.
If this works with written words then it should work with verbal scanning algorithms as well.
