Machine Learning Script Needed!

Hi! I am need of a simple script which will auto detect and solve image based captccha codes with the below example: I have the source code for the captcha. It is very simple - image to text, the text will spell a number between 1-99 which you must type. Eg; if the captcha reads “seventeen” the solution is “17” I would like a script which will auto bypass these captchas within a 5 sec period (the problem refreshes on the website every 10 seconds - tried using API services and these took too long to solve.) It needs to be able to work on firefox v47 / Google Chrome also.
