What is Audio Captcha?
Audio Captcha is a type of CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) that presents a user with a series of spoken words or numbers instead of the traditional image-based CAPTCHA. This method is designed to help visually impaired users verify their human identity while interacting with online forms, including those in
email marketing campaigns.
Why Use Audio Captcha in Email Marketing?
Using Audio Captcha in email marketing serves multiple purposes:
1.
Accessibility: It makes your email sign-up forms more accessible to a wider audience, including those who are visually impaired.
2.
Security: It helps in preventing
spam and bot attacks, ensuring that your mailing list is clean and filled with real human subscribers.
3.
User Experience: Offering an alternative to visual CAPTCHA improves the
user experience for subscribers who may have difficulty with visual tasks.
How Does Audio Captcha Work?
When a user attempts to sign up for your email list, they are presented with an audio clip instead of a visual challenge. The user must listen to the clip and input the spoken words or numbers into a text box to verify that they are human. This helps to ensure that bots cannot easily bypass the verification process.
How to Integrate Audio Captcha in Email Sign-Up Forms?
Integrating Audio Captcha into your email sign-up forms typically involves:
1.
Choosing a Service: Select a CAPTCHA service that offers both visual and audio options, such as
reCAPTCHA.
2.
Implementation: Follow the service's guidelines to add the CAPTCHA to your form. This usually involves adding a few lines of code to your form's HTML.
3.
Testing: Ensure that the CAPTCHA works correctly and does not interfere with the form's functionality. Test it with various screen readers to ensure accessibility.
