|: The reCAPTCHA is a little too hard to read, and the audio was not at all what the words that were written.
That's so it can't be read by computer but only by smart roller skaters. And the audio is just a new challenge which has nothing to to with the visual one.
: I had t refresh to new words just so that I could read it. Also, is it possible to make it just one word each time instead of two??
Not with reCAPTCHA. It presents one word it knows for sure and another one which hasn't been properly recognized by an OCR program. The first word is used to gain trust in you and the second I like to imagine as payment for the service. Incidentally, we profit from the second challenge too, when we download the scanned books.
