How to Transcribe a Large Audio File Completely in Microsoft Word
Question details
The user needs to transcribe a 40-minute audio file, but Word stopped processing after five minutes and will not allow the file to be uploaded again due to size limits.
- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Uploading a long audio recording into the Microsoft Word Transcribe tool.
- Observed behavior
- The transcription process cuts off early, and subsequent upload attempts fail because the system flags the file as too large.
Verify the exact duration and file size of your recording. Microsoft Word's Transcribe feature limits uploads to 200 MB per file and 300 minutes of total audio per month.
Split the Audio File Using Audacity
Dividing the large recording into smaller segments allows you to bypass Word's file size and processing limitations.
When Microsoft Word struggles to process a large audio file in one go, the most reliable workaround is to cut the file into smaller, manageable chunks using a free audio editor.
Download and install Audacity, a free and open-source audio editing utility, to your computer.
Launch Audacity and drag your large 40-minute audio file into the workspace to open it.
Use your mouse to click and drag over the first 10 to 15 minutes of the audio waveform to highlight it.
Go to File > Export > Export Selected Audio, and save this chunk as an MP3 or WAV file.
Repeat the export process for the rest of the file. Open Microsoft Word, go to Home > Dictate > Transcribe, and upload each smaller segment one by one.

Frequently Asked Questions
What is the file size limit for Microsoft Word Transcribe?
Microsoft Word allows a maximum file size of 200 MB for uploaded audio files. If your file is larger, you must compress it or split it into smaller parts.
Why did Word only transcribe the first few minutes of my audio?
This usually happens due to a temporary server timeout, an unstable internet connection, or reaching your monthly upload limit. Splitting the file into smaller chunks helps prevent server timeouts.
Is there a monthly time limit for transcription in Word?
Yes, Microsoft 365 subscribers are limited to 300 minutes of uploaded audio transcription per month. You can check your remaining minutes in the Transcribe pane.
