Dictation does not work on Word; the message that comes up is "something unexpected interupted the audio"

The error indicates that Word’s Dictation feature is losing access to the audio stream, most commonly due to microphone or access issues. Use these steps to troubleshoot:

1. Confirm subscription and version
   • Make sure the account is signed in with an active Microsoft 365 subscription.
   • Verify Windows is Windows 10 or later; Dictation is not available on older versions and is not supported in standalone Office 2016/2019 without Microsoft 365.
2. Check that the document is editable
   • If the Dictate button is grayed out, ensure the document is not in Read-Only state. Save a local copy and try again.
3. Verify microphone access in Windows
   • Ensure the microphone is plugged in (if external) and not muted.
   • Test that the microphone works in Windows (for example, using the built-in microphone test) and that input levels are adequate.
   • In Control Panel, open the microphone settings and confirm the correct device is selected as default and that its input level is not too low.
   • If using a built-in mic, try an external headset or USB microphone.
4. Resolve “no access” or “can’t hear you” situations
   • Close any other apps that might be using the microphone (voice chat, conferencing, recording tools) and then try Dictate again.
   • Move to a quieter location and speak clearly.
   • Adjust the microphone input level higher and test again.
5. If using Word on the web
   • Close other browser tabs or apps that might be using the microphone.
   • Refresh the page, click Dictate again, and when prompted, allow the browser to access the microphone.
6. Network and quality considerations
   • Dictation relies on a stable internet connection. Ensure the connection is fast and reliable and try again.
   • If words are missing or recognition is poor after the error is resolved, reduce background noise and speak more deliberately; consider upgrading the microphone if needed.

If the problem persists after these steps, repeat the microphone tests in Windows to confirm the device is stable, then try Dictation again in a new blank Word document.
