Audio Captchas

[Karthik Vijayarajan]

Hi,
I was trying to implement Captchas in my app. Image Captchas were fairly straight-forward to implement with API's like SimpleCaptcha and JCaptcha. Audio Captchas were not .
JCaptcha has some support for audio captchas but is not well documented. I could not find any sample code. All i could establish so far with JCaptcha was this:

DefaultManageableSoundCaptchaService soundCaptchaService; //injected by spring
AudioInputStream audioInputStream = soundCaptchaService.getSoundChallengeForID(captchaId,request.getLocale());

I could not proceed further. If you have got past this or if you have implemented any other audio captchas, can you please help? Thank you.
