audio CAPTCHAs

Audio CAPTCHAs are security tests designed to verify that a user is human by presenting an audio challenge. They typically involve playing a series of spoken characters or words that the user must recognize and enter correctly. This helps prevent automated bots from accessing websites or services. Audio CAPTCHAs are especially useful for visually impaired users or those with visual disabilities, offering an alternative to visual puzzles like distorted text images. They are designed to be accessible while maintaining security, often including background noise or distortions to differentiate humans from automated programs.
