It is possible to change the language of RadCaptcha by configuring the control to generate the audio code from .wav files
, then create custom audio files for the selected language and point the captcha to the folder with the custom files.
The localization demo of RadCaptcha contains such an example, however only for numbers and for two additional languages: http://demos.telerik.com/aspnet-ajax/captcha/examples/localization/defaultcs.aspx
. Nevertheless, you can utilize this demo as a reference for achieving the desired result when you prepare the custom audio files.
I hope this helps. Feel free to contact us again if you run into more difficulties.
