Screen Reader Testing

With screen reader testing, we evaluate how accessible websites, apps and complex software are for blind and visually impaired people. We assess whether content, navigation and interactive functions can be understood and operated reliably using screen readers such as NVDA, JAWS or VoiceOver.

We examine both technical accessibility and practical usability. Our testing covers semantic structure, focus order, accessible labels and the announcement of dynamic content. This helps identify barriers that visual inspections or automated accessibility checks often miss.

When is screen reader testing useful?

Screen reader testing is useful when companies want to ensure that their digital products are accessible and usable without relying on visual information.

Typical questions include:

• Can blind users navigate and operate our application independently?
• Are headings, buttons and forms announced correctly?
• Are navigation and focus order logical and understandable?
• Do dynamic content and interactive components work with screen readers?

Screen reader testing is particularly valuable for complex applications, interactive forms and custom UI components. It complements WCAG audits and helps identify accessibility barriers early in development.

How do we proceed?

1. Define testing scenarios

Together, we identify relevant user scenarios, functions and target groups. We select suitable combinations of screen readers, browsers and operating systems.

2. Evaluate screen reader accessibility

We test the selected functions using screen readers such as NVDA, JAWS or VoiceOver. Our evaluation covers navigation, semantic structure, accessible labels, focus management and the clarity of announced information.

3. Document and assess barriers

We document identified issues with reproducible steps and relevant technical conditions. Each finding is assessed based on its impact on usability and applicable WCAG success criteria.

4. Recommend and verify improvements

We provide actionable recommendations for design and development. These may include improvements to HTML semantics, accessible labels and keyboard interactions. After implementation, we can retest the affected functions.

What do you receive?

You receive a structured assessment of your digital product's screen reader accessibility.

Depending on the testing scope, the deliverables include:

• Documentation of tested functions and screen reader configurations
• An overview of identified barriers with reproducible steps
• Technical and design recommendations for improving accessibility
• A prioritized foundation for remediation and subsequent retesting

This provides your team with practical insights to improve screen reader usability and make digital products more accessible to blind and visually impaired people.
