Google designed CAPTCHA with distorted background for security reasons.


We use Google CAPTCHA because it is an Internet standard best practice. Anything easier than Google CAPTCHA is easy to hack.

Google’s audio CAPTCHA, have presented overlapping and distorted target voices with stationary background noise to avoid machine to recognize the CAPTCHA voice alone for hacking purposes. That's why google created those CAPTCHE voices along with some distorted noise for security purpose. It's expected behavior.

You can recognize same noise in Google Sign up page.

The audio will have some background noise, Same as how the image is displayed with some distorted background. It won't be an clear audio for the obvious security reasons.
