How to Fix Copilot “Read Aloud” Not Working on Windows 11

The Read aloud feature in Microsoft Copilot is meant to convert on-screen responses into natural-sounding speech, making it useful for accessibility, multitasking, and long explanations. However, on Windows 11, many users report that Read aloud does nothing, produces no sound, or the button is missing entirely.

If Copilot’s Read aloud feature is not working for you, the issue is usually related to audio output settings, system text-to-speech components, language packs, browser/app bugs, or Copilot service limitations.

In this detailed guide, we’ll walk through every effective fix, step by step.

Why Copilot Read Aloud Is Not Working

Copilot Read aloud may fail due to one or more of the following reasons:

• Wrong audio output device selected
• System volume muted or routed incorrectly
• Text-to-Speech (TTS) voices missing or corrupted
• Language mismatch between Copilot and Windows
• Copilot app or browser glitches
• Accessibility services not working properly
• Temporary Microsoft-side service issues

The key thing to understand is that Copilot Read aloud depends on Windows Text-to-Speech and audio services, not just Copilot itself.

Fix Copilot Read Aloud Not Working on Windows 11

Follow the steps below in order. After each step, test the Read aloud feature again.

1. Check System Volume and Audio Output Device (Very Common Issue)

Many users miss this basic but critical step.

1. Click the speaker icon in the taskbar.
2. Make sure the volume is not muted and is set above 30–40%.
3. Click the audio output selector (arrow next to the volume slider).
4. Select the correct output device:
   • Laptop speakers
   • Headphones
   • External speakers

If Copilot is speaking but routed to the wrong device, you won’t hear anything.

2. Make Sure Copilot Audio Is Not Muted in Volume Mixer

Windows allows per-app volume control.

1. Right-click the speaker icon in the taskbar.
2. Click Open volume mixer.
3. Look for Copilot, Edge, or Windows Web Experience Pack.
4. Make sure the volume is turned up and not muted.

If Copilot volume is muted here, Read aloud will silently fail.

3. Verify Text-to-Speech Voices Are Installed

Copilot Read aloud relies on Windows Text-to-Speech voices.

1. Open Settings → Time & language → Speech.
2. Under Voices, check if at least one voice is installed.
3. Click Add voices if none are available.
4. Install a voice such as English (United States).
5. Restart your PC after installation.

Without TTS voices, Copilot has nothing to speak with.

4. Match Copilot Language with Windows Speech Language

Language mismatch can break Read aloud.

1. Go to Settings → Time & language → Language & region.
2. Confirm your Windows display language matches the language you’re using in Copilot.
3. Go back to Speech settings.
4. Ensure the Speech language matches the installed voice.

For example, using English Copilot with a non-English TTS voice can cause silence.

5. Restart Windows Audio Services

Sometimes audio services get stuck.

1. Press Windows + R, type services.msc, and press Enter.
2. Restart the following services:
   • Windows Audio
   • Windows Audio Endpoint Builder
3. Close Services and try Copilot Read aloud again.

This resets all sound-related processes.

6. Restart Copilot and Windows Explorer

Copilot UI glitches can stop Read aloud from responding.

1. Press Ctrl + Shift + Esc to open Task Manager.
2. End the following processes:
   • Copilot (if listed)
   • Windows Web Experience Pack
3. Right-click Windows Explorer → Restart.
4. Reopen Copilot and test Read aloud.

7. Try Copilot in Microsoft Edge (Important Test)

Copilot behaves differently depending on where you use it.

1. Open Microsoft Edge.
2. Open Copilot from the sidebar or web.
3. Click Read aloud on a response.

If it works in Edge but not in the Windows Copilot panel, the issue is with the Windows integration—not audio.

8. Disable and Re-Enable Copilot (Soft Reset)

This refreshes Copilot’s system integration.

1. Open Settings → Personalization → Taskbar.
2. Turn Copilot off.
3. Restart your PC.
4. Go back and turn Copilot on again.
5. Test Read aloud.

This fixes many stuck Copilot UI issues.

9. Update Windows 11 (Very Important)

Read aloud bugs are often fixed silently via updates.

1. Open Settings → Windows Update.
2. Click Check for updates.
3. Install all available updates.
4. Restart your PC.

Outdated builds commonly break Copilot features.

10. Check Accessibility and Narrator Conflicts

Sometimes accessibility tools interfere with Copilot speech.

1. Open Settings → Accessibility.
2. Temporarily turn off:
   • Narrator
   • Speech-related accessibility tools
3. Restart Copilot and test Read aloud.

Running multiple speech engines simultaneously can cause conflicts.

11. Test with a New Windows User Account

This helps identify profile corruption.

1. Create a new local user account.
2. Sign in to the new account.
3. Open Copilot and try Read aloud.

If it works there, your original user profile may be corrupted.

12. Wait and Retry (Microsoft-Side Issue)

In rare cases, Read aloud fails due to backend service issues.

• If Read aloud doesn’t work on multiple devices, browsers, or accounts
• If the button appears but never plays audio

Then the issue may be on Microsoft’s side. Waiting a few hours often resolves it.

Wrapping Up

When Copilot Read aloud is not working on Windows 11, the problem is almost always related to audio output routing, Text-to-Speech voices, language mismatches, or Copilot UI glitches—not your speakers or hardware.

Start with volume and TTS checks, then move through services, updates, and Copilot resets. In most cases, one of these steps restores Read aloud immediately.
