Good to hear.

We're working on improving the audio a bit. We apply 7-out-of-8 matching 
to the result, so it's ok if you miss one for now.

It's very hard to get a secure audio CAPTCHA. Because of automated phone 
systems, commercial technology is available that recognizes human voices 
in noisy situations when there is a fixed range of input.

Did the sound play for you within the browser, or did you have to click 
"can't hear the audio"? If it played within the browser, would you be able 
to replay the sound if needed?

Could you elaborate?

Also, are there any elements of reCAPTCHA solving process that might have 
been made easier (how the buttons were presented, etc)
