Reply To: I realized my mistake, did you realize yours?

I also heard about malachim being created from the words of davening, and the quality of the malach depends on the correctness of the word. but its not a contradiction to what others have mentioned that the tefila is accepted regardless ( not sure about missing a letter in krias shma). i have sources for both, hopefully with time i will post.
The explanation is, there is a difference if the mistake occurred as a result of negligence; being lazy to put in the effort to learn how to read proper, or the mistake occurred as a result of human error although the proper effort was put in, or someone that had started to learn how to read later in life – by no fault of his own – and is in the process of improving his reading.
To a child who we wanto encourage to put in the effort necessary to learn how to read properly, we say how each word creates a malach and the type of malach depends on how he pronounces the word. at the same time someone who did put in the proper effort to read and when davening with proper concentration trying to read each word proper, but by mistake pronounces a word incorrectly, his tefila is accepted.
as i said, hopefully i will post sources for both sides.
