narration into mp3

Copilot narration can be saved as an MP3 in supported audio overview experiences.

For Word or Word for the web:

1. Open the document in Word.
2. Open Copilot from the Home tab.
3. Generate the audio overview.
4. In the audio player, select Expand more options (...).
5. Select Save to OneDrive.

For OneDrive audio overviews:

• The saved audio overview is stored as an mp3 in the Recordings folder.
• Save to OneDrive is available only for non-encrypted files.
• If the file is encrypted, the audio overview cannot be saved.

Important limits:

• Supported for English files only.
• The file must have at least 200 words.
• Generation can take a few minutes.
• Audio overview generation may be subject to daily usage limits.

If the goal is to extract narration from a video created in the Microsoft 365 Copilot app, that flow is different: open the video in Clipchamp with Edit in Clipchamp, then Export it. The provided content does not describe exporting audio-only MP3 directly from that Copilot video flow.
