PHP Sound Captcha

PHP Sound CaptchaSoundCaptcha is simple form for verification of any “token” in case that submitted request is human input. 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”.

SoundCaptcha spells letters from A-Z and numbers from 0 to 9, but it simply ignores other characters such as !@#$%^… etc. You may choose whether captcha audio player will open in Pop-up window or current captcha page. Captcha string its case InSeNsItIvE and this ensures that user doesn’t have to be worried about case sensivity.
