Enter a number from 1 to 999999999999999999999 (or (10^21)-1) and it will speak it out loud.
Feel free to use this script in your games or anything. Please tell me any numbers up on which it messes, especially with the green highlighter. I have now fixed various different glitches, especially a glitch for the number 09876543445. The green highlighter thing can be confusing with lots of zeros. Please comment (I love to hear what you think!) and, if you liked it, love and favourite!
