Text to Speech for Accessibility

Text to speech is a practical accessibility aid for people with visual impairments, reading disabilities like dyslexia, cognitive processing differences, or motor disabilities that make reading difficult. It turns written content into audio that can be consumed independently. Coda One's browser-based TTS tool lets people start with pasted text directly on the page, without a software installation step.

Accessibility-focused TTS use goes beyond simple screen reading. Users with dyslexia often find that hearing text while reading it simultaneously improves comprehension significantly. People with low vision may prefer TTS over screen magnification for longer documents. Those with attention deficit conditions use TTS to maintain focus on content that would otherwise lose their attention as text. Speed control (0.5x to 2x) lets each user find their optimal listening pace, and voice selection helps find the voice that's clearest for their specific needs.

Because our tool runs entirely in the browser using the Web Speech API, it works without installing any software — critical for users on shared or managed computers where installing screen readers isn't an option. It handles any text pasted into it, from web articles to emails to documents, providing an instant audio version. The download feature lets users save audio for offline listening, creating portable accessible versions of any text content. The browser-based flow also avoids sending that text to our servers during playback.
