# Screen Reader Simulation Tester Simulate the reading order and spoken semantics a screen reader may expose from a URL or raw HTML, then flag likely accessibility gaps > Canonical page: https://elysiatools.com/en/tools/screen-reader-simulation-tester - **Category:** Validation - **Keywords:** screen reader, accessibility, aria, voiceover, nvda, html semantics ## Overview Paste raw HTML or provide a live URL. The tool extracts a likely screen-reader reading order, then shows what blind users may hear first: page title, landmarks, headings, links, buttons, form labels, images, and list items. How to use it: - HTML Input: paste raw markup when you want deterministic analysis - Page URL: optional live page URL to fetch and inspect - Screen Reader Preset: changes the phrasing style only; the semantic analysis stays the same - Include Landmark Summary: adds navigation/main/footer landmark summaries - Show Fix Suggestions: includes repair guidance beside each issue What the report highlights: - Likely spoken order in document flow - Heading hierarchy and skipped levels - Missing aria-label or form-label coverage - Missing or empty image alt text - Unlabeled links and buttons Notes: - This is a semantic simulation, not a pixel-perfect reproduction of NVDA, JAWS, or VoiceOver - Dynamic client-side state that only appears after scripts run may not be visible unless the HTML already contains it ## Inputs - **HTML Input** (textarea): # Pricing \[Start trial\](/checkout) - **Page URL** (text): https://example.com - **Screen Reader Preset** (select) - **Include Landmark Summary** (checkbox) - **Show Fix Suggestions** (checkbox) ## When to use - Auditing web pages for accessibility compliance and semantic structure before deploying to production. - Debugging complex HTML forms to ensure all inputs, buttons, and controls have proper accessible names. - Verifying the heading hierarchy and landmark navigation of a layout to prevent screen reader confusion. ## How it works - Paste your raw HTML markup or provide a live page URL for the tool to inspect. - Select a screen reader preset (NVDA, JAWS, or VoiceOver) and toggle landmark summaries or fix suggestions. - The tool parses the document flow, extracting the likely spoken order of headings, links, forms, and images. - Review the generated report to identify missing alt text, skipped heading levels, and unlabeled controls. ## Use cases - QA testers verifying WCAG compliance for e-commerce checkout flows. - Frontend developers checking the accessibility of custom UI components and interactive widgets. - Content managers ensuring blog posts have proper heading structures and image alt text. ## Frequently asked questions ### Is this a perfect replica of NVDA or VoiceOver? No, this is a semantic simulation. It approximates the reading order and spoken output based on HTML semantics, but actual screen reader behavior may vary slightly depending on user settings and browser combinations. ### Can it analyze dynamic content loaded via JavaScript? The tool analyzes the HTML provided. If you use the URL input, dynamic client-side state that appears only after scripts run might not be captured. For dynamic states, paste the fully rendered HTML directly into the input. ### What does the Screen Reader Preset option do? The preset changes the phrasing style of the output to match the typical announcement patterns of NVDA, JAWS, or VoiceOver. The underlying semantic analysis and issue detection remain the same. ### Why is my heading hierarchy flagged as an error? Screen reader users rely on headings to navigate a page. The tool flags skipped levels (e.g., jumping from H1 directly to H3) because it breaks the logical document outline and makes navigation confusing. ### How do I fix unlabeled buttons in the report? If you enable 'Show Fix Suggestions', the tool will provide specific guidance. Typically, you need to add visible text inside the button, an aria-label, or an aria-labelledby attribute. ## Related tools - [Heading Hierarchy Auditor](https://elysiatools.com/en/tools/heading-hierarchy-auditor): Audit heading structure from a live URL or pasted HTML, then flag skipped levels, multiple h1 usage, style-only heading abuse, and title metadata drift - [AsciiMath LaTeX MathML Equation Converter](https://elysiatools.com/en/tools/asciimath-latex-mathml-equation-converter): Convert equations between AsciiMath, LaTeX and MathML: auto-detect the input format, produce canonical LaTeX, presentation MathML with an embedded TeX annotation, a best-effort AsciiMath back-translation, a screen-reader aria-label snippet (role=math), and a KaTeX HTML preview. - [Accessibility Checker](https://elysiatools.com/en/tools/accessibility-checker): Detect common WCAG 2.1 accessibility issues in HTML, fetched pages, or design images and return fix-ready guidance - [Image Source Extractor](https://elysiatools.com/en/tools/image-source-extractor): Extract image URLs (src attributes) from HTML source code.
