Simple HTML Form with CAPTCHA Image
A CAPTCHA is a program that can generate and grade tests that humans can pass but current computer programs cannot. We need to add CAPTCHA validation on common form like contact us, enquiry Preventing Comment Spam in Blogs. Most bloggers are familiar with programs that submit bogus comments, usually for the purpose of raising search engine ranks of some website (e.g., “buy penny stocks here”). This is called comment spam. By using a CAPTCHA, only humans can enter comments on a blog. There is no need to make users sign up before they enter a comment, and no legitimate comments are ever lost!

SoundCaptcha - Captcha that speaks.
We all know that todays captchas generate string that most of times are hard to read from eye of human and this requires that the page must reload (refresh) to generate new captcha string, and after refreshing page you may lost some of information you’ve already wrote in the input fields, meanwhile this creates frustration to you as user. For this reason SoundCaptcha offers the second chance, possibility to hear captcha token via voice speaker then type it on the captcha input field, and this increases the probability that user will type the correct required “token”.
