A site for solving at least some of your technical problems...
It took me a little time, but I finally search and found the reCAPTCHA.
The default CAPTCHA for Drupal looks awful. It is called Image and creates very ugly extremly hard to read images. So I always wanted to switch to reCAPTCHA that is not perfect but looks a lot better and has audio availbale.
So today I found it, it is here: http://drupal.org/project/recaptcha
Note that you still need the CAPTCHA system, it just adds one more option which is reCAPTCHA instead of Image. (at leat, that the way I use it.)
The CAPTCHA system is available here: http://drupal.org/project/captcha
Looking at it a little closer, there are also modules with other CAPTCHA extensions: more complex math, more letters from words, more phrases, questions/ansers...
The reCAPTCHA is still the one I prefer.
