How to Transcribe and Summarize a Voice Memo With ChatGPT (Step by Step)

To transcribe and summarize a voice memo with ChatGPT, upload the audio file to a chat (for example the M4A file from your phone's voice recorder) and ask: "Transcribe this, then summarize it in 5 bullet points." Audio uploads have been available since October 6, 2026, on paid ChatGPT plans (not on Free). Files can be up to 512 MB. This guide shows the exact steps and ready-to-copy prompts for students and freelancers. Details come from OpenAI's help center, checked on November 10, 2026.

What You Need

OpenAI also says availability can depend on your region, app version and model, and that transcripts may contain errors, especially in some languages.

Step 1: Get the Audio File From Your Phone

1. iPhone (Voice Memos): open the recording, tap the three dots, then Share and Save to Files. Voice Memos saves recordings as M4A, which ChatGPT supports
2. Android: most recorder apps save M4A or MP3. Use the app's Share button, or find the file in your Files app
3. Meeting recordings (Zoom, Google Meet, Teams): download the audio-only file if you can. If you only have a video, export the audio first
4. WhatsApp voice notes: these are usually .opus files. If one does not upload, convert it to MP3 or WAV first

Step 2: Upload the Recording to ChatGPT

1. Open ChatGPT on the web, the desktop app or the mobile app
2. Start a new chat
3. Click the + (attach) button and choose your audio file, or drag the file into the chat window on a computer
4. Wait for the upload to finish, then type your request

Step 3: Get a Clean Transcript

Ask for the full text first. That way you can check it before you summarize.

Transcribe this recording word for word.
Keep the original language. Add paragraph breaks when the topic changes.
If there are several speakers, label them Speaker 1, Speaker 2.
Mark any part you cannot hear clearly as [unclear].

Tip: read the transcript once and fix names, brands or numbers ChatGPT may have misheard. Speaker labels are not always right, so check who said what. Then ask the next questions in the same chat.

Step 4: Summarize the Voice Memo

Summarize this recording in:
1. One sentence: what it is about
2. 5 key points
3. Decisions made
4. Action items with who does what and when (if mentioned)
Keep it short and use simple words.

Step 5: Turn It Into Something Useful

The real time-saver is what you do after the summary. You can ask questions about the recording, like "What did we decide about the price?" or "Find where we talked about the deadline."

On the Free Plan? Do This Instead

Audio uploads are not available on ChatGPT Free. You can still get the summary for free:

1. Get a text transcript from your phone or recorder app if it offers one, or from a free transcription tool
2. Copy the text and paste it into ChatGPT
3. Use the same summary and study prompts from this guide

Recording a meeting live instead? ChatGPT also has a separate Record mode in the ChatGPT desktop app for macOS, on Plus and higher plans, that records, transcribes and summarizes meetings of up to 4 hours.

Problems and Quick Fixes

Privacy and Accuracy: Read This First

• Ask before you record people. Tell others when a call is recorded, and follow your local rules
• Avoid uploading very sensitive recordings, such as passwords, health or banking details
• Check your data settings. In ChatGPT, open Settings, then Data controls, to choose whether your chats can be used to improve OpenAI's models
• Always check important facts. Transcripts can contain mistakes, so verify numbers, names and decisions before you send anything
