Five ways to transcribe audio to text at a glance

How to transcribe audio: the steps that work for every method

Whichever tool you pick, the process has the same five steps.

1. Start with a clear recording. Place the microphone close to the speaker and cut background noise before you press record.
2. Save the file in a common format. MP3, WAV and M4A are accepted almost everywhere. Microsoft Word accepts .wav, .mp4, .m4a and .mp3.
3. Choose the language. Most tools ask for it, and a wrong choice returns a poor transcript.
4. Upload or import the file. Keep the page open while it processes if the tool asks you to.
5. Review and export. Read the transcript against the audio for names, numbers and technical terms, then save it as text, Word or PDF.

Transcribe audio to text free: what you can do today

Free tools cover most one-off jobs. You upload a file, wait a few minutes, and copy the text.

A free upload tool. Wave's free transcription page is a clear example. You upload an audio or video file in m4a, mp3, wav, mp4, webm and other formats, up to 200MB each, with no account and no watermark. You can transcribe up to five files per day. The output includes each speaker labeled and timestamped, plus an AI summary with action items, and you can choose from 15 languages or let the tool detect the language. Other upload tools work in a similar way, so check each one's file limit, daily limit and language list before you start.

Microsoft Word. If you have a Microsoft 365 subscription, Word can transcribe audio without a separate service. Go to Home, open the Dictate drop-down, and choose Transcribe. In the Transcribe pane, select Upload audio and pick a file. Word transcribes .wav, .mp4, .m4a and .mp3 files. Users with a Microsoft 365 subscription can transcribe up to 300 minutes of uploaded audio a month, and users with a Microsoft Copilot license can transcribe up to 30,000 minutes a month.

A free tier of an AI app. Otter's Basic plan is free and includes 300 transcription minutes a month, with 30 minutes per conversation and three imported files in total. It suits a few short recordings.

The limits to watch are file length, files per day, and how many imports the free plan allows over its lifetime.

How to transcribe audio to text in Microsoft Word

To transcribe audio to text in Word, go to Home, open the Dictate drop-down, choose Transcribe, upload an audio file, and read the transcript in the program where you write.

1. Open Word and go to Home, then the Dictate drop-down, then Transcribe.
2. In the Transcribe pane, choose Upload audio, or choose Start recording to record in Word.
3. Pick the file. Keep the Transcribe pane open while it processes. Transcription can take up to about the length of the audio.
4. When it finishes, read the transcript. Word separates each speaker and labels them Speaker 1, Speaker 2 and so on.
5. Edit the content of any section, or change a speaker label. Select Change all Speaker to rename every occurrence at once.
6. Save the full transcript as a Word document, or insert snippets into an existing document.

Word saves the audio to a Transcribed Files folder in OneDrive, and you can delete it there. You can play it back at up to 2x speed and select any timestamp to jump to that part of the audio. The feature is available in Word for Microsoft 365 on Windows in commercial tenants, and government tenants have it in Word for the web.

AI transcription: when an app makes sense

Use an AI transcription app when you have recordings every week, not once. The software turns speech into text, and most apps add speaker labels, timestamps, search and a summary.

What to compare:

• Minutes included. Free tiers cap monthly minutes, and paid tiers raise the cap or remove it.
• File and conversation length. A free plan with a 30-minute limit per conversation will not handle a two-hour interview.
• Imports. Some plans limit how many existing audio files you can bring in, which matters if you have a backlog.
• Languages. Check the list for the language you record in.
• Export formats. Word, PDF and text exports save editing time.
• Privacy. Look for a clear statement on how recordings are stored and who can access them.

Our Otter AI pricing guide shows how one app breaks these limits down by plan.

Transcription services: when a person checks the text

A human transcription service fits material where an error has a cost, such as legal proceedings, medical records and published interviews, because people type or review the transcript. Prices are quoted per audio minute and turnaround is longer than with AI. For most business recordings, an AI transcript plus your own review is faster and costs far less.

Transcribe audio to text on your phone

On an iPhone 12 or later, the Voice Memos app transcribes speech in English (all variants), Spanish, Portuguese, Italian, French, German, Japanese, Korean, Simplified Chinese and Traditional Chinese. Open a recording, tap the options button, and choose View Transcript. You can copy part of the text or the whole transcript and paste it into Mail or a document. Recordings made in iOS 17 or earlier are transcribed automatically when you open them, as long as they include speech. For the Voice Memos steps in full, read How to transcribe voice memos.

On any phone, the other route is to share the audio file to an upload tool or an AI app. Save the recording to Files or send it by email, open the tool in your browser or app, and pick the file. Keep the phone plugged in or on Wi-Fi for long files so the upload does not stall.

Audio to text converter checklist

Before you trust an audio to text converter with an important file, run through these questions.

• Does it accept your file format? MP3, WAV and M4A are the safest choices.
• What is the size or length limit? Wave allows 200MB per file and five files a day on its free page, and Otter's free plan allows 30 minutes per conversation.
• Does it label speakers? Interviews and meetings are hard to read without speaker labels.
• Does it support your language? Wave offers 15 languages on its free page, and Comu supports 113.
• Can you export what you need? Look for Word, PDF or plain text, and a way to keep the audio.
• Where does the file go? Word stores uploaded audio in a Transcribed Files folder on OneDrive, and you can delete it there. Check the same detail for any other tool.
• What happens when you have more files? Daily caps and import limits decide whether a free tool still works next month.

Common problems and how to fix them

• Wrong language selected. Set the language to the one spoken and run the file again.
• Background noise or echo. Record again closer to the speaker, or move to a quieter room.
• Overlapping speakers. Ask people to take turns when you can. When you cannot, review the overlapping sections by hand.
• File too large or too long. Split the recording into parts and transcribe each one.
• Names and technical terms misheard. Read the transcript once and correct them. Word lets you edit any section and rename a speaker across the whole transcript.
• Upload stalls. Keep the page open, use a stable connection, and retry with a smaller file.

Tips for a cleaner transcript

Quality starts at the recording, and a few habits improve any audio to text transcription.

1. Keep the microphone close. Within arm's length of the speaker is a good rule.
2. Control the room. Close windows, turn off fans, and avoid hard, echoing rooms.
3. One voice at a time. Ask people to take turns.
4. Say names and numbers clearly. Spell unusual names once at the start.
5. Match the language setting. Set the transcription language to the one spoken.
6. Split very long files. Smaller files are easier to review and avoid upload limits.
7. Read the transcript once. A short review catches mistakes before you share the text.

What it costs to transcribe audio over three years

Over three years, Comu Note Pro costs €139.99 and Comu Action Pro costs €179.99 with the free plan. Otter Pro costs $299.88 on yearly billing or $611.64 on monthly billing over the same three years. Comu prices are euro prices from the EU store (Nov 6, 2026); competitor prices are US dollar prices from each company's own site. Totals are cumulative: the Comu rows are the device price plus the €0 free plan, and the Otter rows are subscription fees. Free tools cost nothing for light use.

The Comu rows use only what the free plan that comes with the device includes: unlimited transcription, unlimited real-time transcription, speaker identification, summaries, action items, templates and imports of external audio files. Otter Basic stops at 300 transcription minutes a month and 30 minutes per conversation and allows three imported files in total. Otter Pro gives 1,200 minutes a month and 10 imports a month, so the table compares Comu with Otter Pro.

Audio to text transcription with Comu AI

Comu AI turns audio into text by recording the conversation or importing an audio file, then transcribing it, labeling the speakers, and writing the summary and action items.

Comu is a pocket recorder with an app. You record a meeting, interview, lecture or phone call from a device in your pocket, and the transcript and summary arrive in the app. The Comu app also imports external audio files, including iPhone voice memos, so recordings you already have go through the same workflow. The plan that comes with the device includes:

• Unlimited transcription, with unlimited real-time transcription, so a two-hour interview costs nothing extra.
• Speaker identification, which labels who said what.
• AI summaries and action items, generated from the transcript.
• Templates, with 30+ built in and unlimited custom templates, to produce meeting minutes, interview notes or a follow-up email.
• 113 languages.
• Exports to TXT, Markdown, Word and PDF for text, and MP3 and WAV for audio.

Comu Note Pro is €139.99 and Comu Action Pro is €179.99 (Nov 6, 2026).

If you transcribe audio now and then, a free upload tool is enough. If transcripts are part of your week, a recorder that produces the transcript, speaker labels and summary in one step saves the upload, wait and copy-paste cycle each time. For a closer look, read our guide to the features that come with Comu, or look at Comu Note Pro and Comu Action Pro.

Which method to choose

Common questions about transcribing audio to text

How do I transcribe audio to text?

Record or save the audio as an MP3, WAV or M4A file, upload it to a transcription tool, choose the language, wait for the result, and review the text. Microsoft Word, free upload tools and AI apps all follow these steps.

How can I transcribe audio to text for free?

Use a free upload tool, the transcribe feature in Microsoft Word if you have Microsoft 365, or the free tier of an AI app. Wave's free page allows up to five files a day at 200MB each with no account, and Otter's free plan includes 300 minutes a month.

Can Microsoft Word transcribe audio?

Yes. In Word for Microsoft 365, go to Home, open the Dictate drop-down, and choose Transcribe, then upload an audio file or record in Word. It supports .wav, .mp4, .m4a and .mp3 files and allows up to 300 minutes of uploaded audio a month with a Microsoft 365 subscription.

What is the best audio to text converter?

A free upload tool fits one file, Word fits people already on Microsoft 365, an AI app fits weekly meetings, and a recorder with built-in transcription fits in-person conversations and calls.

How accurate is AI transcription?

Accuracy depends on audio quality, background noise, accents and the number of speakers. Clear audio with one speaker at a time gives the best result, and a quick read-through of the transcript catches the remaining errors.

What audio formats can I transcribe?

MP3, WAV and M4A are accepted by most tools. Microsoft Word accepts .wav, .mp4, .m4a and .mp3, and Wave accepts m4a, mp3, wav, mp4 and webm among others.

Can I get a summary and action items, not just a transcript?

Yes. Some tools add an AI summary with action items, including Wave's free page. Comu generates a summary and action items for every recording, with speaker labels and templates.

How do I transcribe audio with multiple speakers?

Choose a tool that labels speakers. Word marks them Speaker 1, Speaker 2 and so on, and lets you rename them. Comu includes speaker identification, and Wave labels each speaker with a letter.
