Artificial intelligence (AI) is all the rage now, with even Apple embracing it. AI was prominent in most of the features promised by that the US tech giant. Generative AI (Gen AI) is a key factor in various sectors as it has a great potential to revolutionize any industry. It can help organizations to automate, identify and remediate accessibility barriers. Furthermore, Gen AI can also streamline compliance with accessibility standards and can customize content to suit a diverse user base.
In this blog, we will explore how Generative AI can transform web accessibility testing.

What is Accessibility Testing?
Accessibility testing is crucial for ensuring that digital products are usable by individuals with disabilities. This process evaluates how accessible these products are for people with visual, auditory, motor, or cognitive challenges, identifying and resolving any barriers that might hinder their ability to access or interact with the content.
Developers can foster a more inclusive digital environment by assessing factors such as color contrast, providing alternative text for images, correctly implementing ARIA roles, and testing keyboard usability. This process is vital not only for compliance with legal standards but also for creating an inclusive user experience and demonstrating corporate social responsibility.
To conduct effective accessibility testing, companies must familiarize themselves with accessibility guidelines and regulations, utilize specialized automated testing tools, and perform manual assessments.
Involving users with disabilities in the testing process is also essential. By doing so, organizations can create digital products that are both accessible and inclusive for a diverse range of users.
How Does Accessibility Testing Work?
Accessibility testing can be divided into several stages:
- Understanding and Planning: The process of accessibility testing involves understanding the project’s scope, identifying the target audience, and selecting appropriate accessibility guidelines and standards. Familiarizing oneself with the Web Content Accessibility Guidelines (WCAG) is the first step, as it provides comprehensive guidelines for creating accessible digital content, helping testers identify potential issues and ensure compliance.
- Automated Testing: Automated tools are used to scan websites and applications for common accessibility issues, such as missing alt text, insufficient color contrast, and improper use of ARIA roles. These tools provide quick feedback on areas needing improvement, ensuring that websites and applications are accessible and user-friendly.
- Manual Testing: Automated tools are useful, but they cannot catch all accessibility issues. Manual testing uses assistive technologies like screen readers, keyboard navigation, and voice recognition software to identify these issues. Human testers use these technologies and perform tasks like keyboard navigation, color contrast adjustment, and text resizing to ensure usability for users with disabilities.
- Compatibility and User Testing: The testing process for digital products requires real users with disabilities, who provide valuable feedback on usability and accessibility. Accessibility testing evaluates the product’s performance across various devices, operating systems, and browsers, ensuring accessibility for all users.
- Remediation and feedback loop: It starts providing recommendations for fixing issues and implementing fixes are crucial for the development team. However, one must not forget that accessibility is an ongoing process. Therefore, it requires regular testing and monitoring as products evolve and new features are added. A feedback loop should be established so that the whole team is on the same page.
Limitations of current tools
Automated testing utilizes accessibility tools, but keep in mind that they are just one component of a comprehensive approach. Relying solely on these tools as indicators of compliance can create a misleading sense of security. They might misrepresent a website or app as fully accessible for individuals with disabilities, despite existing issues.
Some common issues that automated accessibility tests might miss:
- Automated tools also struggle to evaluate whether content is clear, concise, and easily understandable for the average reader.
- Automated tools may also offer false positives — they may indicate that a certain element creates an accessibility barrier, but the element might not affect the on-page experience for real users.
Some issues that manual accessibility tests might miss:
- Manual testing often takes longer than automated testing. Finding testers and completing the testing process can be a lengthy endeavor.
- The outcomes of manual testing can vary due to human error.
- The findings from manual testing depend on the tester’s experience and perspective.The results of manual testing are based on the tester’s experience.
Benefits of using Gen AI
Generative AI can play a key role in developing digital accessibility solutions. These could include speech-to-text and image-to-speech technologies, as well as enhancing accessible design features such as adaptive text, fonts, and color schemes that support individuals with reading, visual, or cognitive impairments. Additionally, similar AI-driven algorithms can be applied to create libraries, knowledge-sharing platforms, and educational tools that promote assistive accommodation, social protection, micro-learning, and even equality training and enforcement.
