AI-Generated Alternative Text (ALT Text)
Building upon its initial support for manual ALT text on images, TikTok is now testing AI-generated ALT text that automatically describes photos when creators do not provide manual descriptions. This feature ensures that screen reader users receive descriptive information about visual content, even in the absence of user-provided captions. Creators retain the ability to edit or add ALT text post-upload, allowing for accuracy and personalization. Tech Edition+9The Verge+9TechCrunch+9
Enhanced Visual Accessibility Features

- Color Contrast Toggle: Users can now increase the foreground color of text, icons, and user interface elements, enhancing visibility for those with low vision or contrast sensitivity. TechCrunch+3The Verge+3Newsroom | TikTok+3
- Bold Text Support: TikTok detects if a user’s device has bold text enabled and automatically displays all in-app text in bold, improving readability for users who prefer or rely on bolder fonts. The Verge+5Newsroom | TikTok+5Newsroom | TikTok+5

AI-Powered ALT Text: How It Works
The new AI-driven system automatically generates descriptions for videos, allowing screen readers to convey the content to users who can’t see it. Here’s a breakdown:
- Automatic Generation: The AI analyzes video content and creates descriptive ALT text without requiring creators to manually input descriptions. This makes accessibility a default feature, encouraging broader adoption.
- Improved User Experience: Visually impaired users gain a better understanding of video content through detailed audio descriptions.
Other Accessibility Tools on TikTok
Besides AI-generated ALT text, TikTok offers other tools to enhance accessibility:
- Text-to-Speech: This feature converts text on the screen into spoken words, aiding users who have difficulty reading.
- Adjustable Playback Speed: Users can slow down or speed up videos to better understand the content.
- Subtitles and Captions: TikTok supports subtitles and captions, making videos accessible to users who are deaf or hard of hearing. Creators can add captions to their videos or use auto-generated captions, which they can then edit for accuracy.
Industry Impact and Future Implications
TikTok‘s investment in accessibility features sets a positive example for other social media platforms. As AI technology continues to evolve, we can expect even more sophisticated accessibility tools to emerge, making digital content more inclusive and accessible to all.
