As such, sites implementing CAPTCHAs may provide an audio version of the CAPTCHA in addition to the visual method. The official CAPTCHA site recommends providing an audio CAPTCHA for accessibility reasons. Why should I have to explain something that is widely known and easy to find? Please do the reading before telling people such things are nonsense.
