Page Zoom now lets you increase the size of the text you see in Chrome on Android without affecting the webpage layout or your browsing experience — just like how it works on Chrome desktop.
Why These Smarter Accessibility Tools Upgrades Matter
Leveraging AI and machine learning, Google’s enhancements aim to empower users with visual, hearing, and language-related impairments, reducing reliance on workarounds or third-party apps. By integrating capabilities like Gemini-powered image descriptions, expressive captions, and OCR directly into system tools, Google ensures consistency and security across apps. Furthermore, extending speech recognition to under-represented African languages fosters greater inclusivity in emerging markets, aligning with global accessibility goals.
1. Preparing Your Device
Before diving into individual features, ensure your device and apps are up to date.
Open Google Play Store and tap your Profile icon.
Select Manage apps & device → Updates available, then update both Android Accessibility Suite and Google Chrome.
Restart your device to apply changes.
Tip: On Chrome desktop, click the three-dot menu → Help → About Google Chrome to check for updates and relaunch if needed .

2. Activating Gemini-Powered Image Descriptions in TalkBack
TalkBack now taps into Google’s Gemini AI to offer detailed descriptions of images and answer follow-up questions.
Go to Settings → Accessibility → TalkBack.
Tap the Settings (gear) icon within TalkBack, then choose Image descriptions.
Toggle Ask Google for image descriptions on.
To use, open any image in an app or browser, swipe right until you hear “Describe image,” and double-tap. Gemini will narrate what it sees and you can ask follow-up queries like “What color is the car?”.
Pro Tip: This feature works offline using Gemini Nano for faster response times.
3. Enabling Expressive Captions for Richer Context
Expressive Captions on Android and Chrome bring tone, background sounds, and emotion into live captions.
Navigate to Settings → Accessibility → Live Caption.
Ensure Use service is turned on.
Under Advanced, activate Capture tone and Show background sounds.
Media playing on your device (videos, calls, podcasts) will now include expressive captions that denote laughter, sighs, and ambient noises for a fuller experience.
Note: Expressive Captions require Android 14 or later on supported devices and may vary by region.
Have you ever thought about what stands between your personal information and the endless threats lurking online? Whether it’s your bank details, social media accounts, or simply browsing habits, there’s a lot at stake. And with options like McAfee Total Protection 3-Device 2025 Ready, the choice can feel overwhelming. But is it the right choice for you?
4. Using Built-In OCR for Scanned PDFs in Chrome
Gone are the days of inaccessible scanned documents—Chrome’s OCR integration makes text selectable and screen-reader compatible.
Open Chrome (desktop or Android) and tap the three-dot menu → Settings → Accessibility.
Enable Text extraction from images or Recognize text in scanned PDFs.
Load any scanned PDF; Chrome will automatically run OCR, allowing you to highlight, copy, search, and have screen readers read the text aloud.
Workflow Tip: After text extraction, right-click (desktop) or long-press (Android) any word to see options for search, copy, or translation.
5. Customizing Page Zoom Without Layout Breaks
Adjust text size on web pages without disrupting the overall layout, perfect for low-vision users.
In Chrome for Android, go to Settings → Accessibility.
Under Page zoom, drag the slider to increase or decrease zoom level globally or per site .
Browse as usual—text enlarges while images and design elements remain proportional, preserving readability and navigation.
SEO Note: This feature aligns with “mobile-first” design recommended by Google, ensuring content remains accessible across all devices.
6. Expanding Speech Recognition to African Languages
Google is democratizing voice input by adding support for ten African languages through open-source datasets and developer tools.
Go to Settings → System → Languages & input → Voice input.
Tap Offline speech recognition → All languages, then find and download your desired African languages (e.g., Swahili, Yoruba).
In any app that supports dictation, select the new language for voice typing. The engine will transcribe non-standard speech patterns more accurately.
Developer Insight: Google.org’s partnership with UCL and local African universities under Project Euphonia aims to refine models using community-sourced speech data.
