We tried using jcaptcha Audio Capthca API(http://jcaptcha.sourceforge.net/) for implementing the Audio Validation on one of the sites. Challenges is it is not consistently working across different browsers, operating systems. Works on IE. Does not work on mozilla, chrome. Is there is any alternate proven good solution to replace jcaptcha with which works across multiple browser, multiple platform.
Any ideas, suggestions, sample code, links, source code highly appreciated. Thanks in advance
