Text to Speech for Accessibility

Make your digital content accessible to everyone with free, offline text-to-speech. Our tool generates natural-sounding audio alternatives for websites, documents, and applications — helping you meet WCAG 2.1 and ADA accessibility requirements.

Accessibility and TTS: The Web Content Accessibility Guidelines (WCAG) 2.1 Success Criterion 1.1.1 requires text alternatives for non-text content, and Success Criterion 1.2.1 requires audio alternatives for time-based media. Text-to-speech is a core accessibility technology that converts written content into spoken audio for users who:

• Have visual impairments — screen readers and audio alternatives provide access to written content
• Have reading disabilities — dyslexia, ADHD, and other conditions that make reading difficult benefit from audio alternatives
• Prefer auditory learning — some users comprehend and retain information better when they hear it
• Are on mobile devices — audio is easier to consume on small screens in motion
• Have limited literacy — audio provides access regardless of reading level

Why OfflineTTS is ideal for accessibility:

• No server dependency — works offline after model download, ensuring reliable access
• No cost barrier — completely free, removing financial obstacles to accessibility compliance
• No data collection — sensitive user content never leaves the device
• 9 languages supported — multilingual accessibility for diverse user populations
• WAV and MP3 export — standard audio formats compatible with all assistive technologies
