Making conversational interfaces work with screen readers

Creating accessible chat interfaces requires understanding how screen reader users experience conversations. Unlike visual users who scan messages, screen reader users hear content in sequence, making organization especially important.

Key accessibility considerations for screen reader users include:

• Clear structure: Use proper headings to distinguish between user and AI messages
• Speaker identification: Include clear labels for who is speaking in each message
• Descriptive elements: Ensure all buttons and interactive elements have clear labels
• Alternative text: Provide text alternatives for any images or icons
• Hierarchical descriptions: Create structured descriptions for complex visuals like charts
• Timing control: Avoid rapid message sequences that create overwhelming output

Testing with actual screen readers is essential rather than relying only on simulation tools, as implementation details significantly affect usability. Include users with visual impairments throughout design testing to identify issues that automated tools might miss. This approach creates conversation experiences that work well for everyone.
