Hi,

First of all to check the accuracy you should have both - recognized text and the original text if you dont have the original text you have to type it then follow these psuedo code:

all_orig_text.split(" ");

all_recog_text.split(" ");

countofcorrect = 0;

for (int = 0; i < all_orig_text.length ; i++)

          if (all_orig_text[i] == all_recog_text[i]) //this will help to check accuracy word wise

                countofcorrect++;

ratio = countofcorrect /  all_orig_text.length *100

you have to improve this code to suit your needs
