ScreenVox PRO

NVDA & JAWS screen reader emulator with WCAG testing. Free with PRO upgrade. © otratarea.com 2026

Screenvox PRO brings screen reader testing directly to your browser. Navigate any webpage exactly as NVDA and JAWS users do—with voice announcements, element highlighting, and keyboard-equivalent navigation—all from a compact panel that opens over your active tab.

Beyond Emulation: In addition to manual scanning, the extension includes an automated WCAG 2.2 audit engine that checks 14 categories of accessibility criteria at A, AA, and AAA conformance levels, and allows exporting a detailed CSV report.

Web Developers: Detect accessibility issues before they reach production. 

Accessibility Consultants: Quickly triage websites with exportable CSV evidence. 

QA Engineers: Add screen reader testing to your workflow without installing NVDA or JAWS. Students and Educators: Learn how screen readers interpret HTML structure.

Switch between two reader modes. Each mode presents a clickable button panel matching the exact keyboard shortcuts of that screen reader.

🔊 Configurable Voice
