How to Transcribe Audio to Text: 4 Free Methods Compared

If you need to transcribe audio to text, you have more free options than you might think. The right one depends on a simple question: do you already have an audio file, or are you recording right now?

This guide compares four methods, explains what each one is good at, and shows where each one stops working.

Quick answer

If you already have an MP3, M4A, WAV, or video file, skip to method 4.

Method 1: Use your phone's built-in recorder

Recent phones can transcribe recordings made in their own recorder apps:

• iPhone: the Voice Memos app can show a transcript for recordings in supported languages on recent iOS versions. Open a recording and tap the transcript icon.
• Google Pixel: the Recorder app transcribes while you record and lets you search the text later.

Good for: quick voice notes and reminders you record yourself.

Limits: these features only work on recordings made in that app, support a limited set of languages, and are not built for exporting a clean document. They also cannot transcribe a file someone sent you.

Method 2: Google Docs voice typing

In Google Docs, open Tools > Voice typing in Chrome and start speaking. Your words appear in the document as you talk.

Good for: dictating a draft instead of typing it.

Limits: voice typing listens to your microphone in real time. It cannot open an audio file. Playing a recording through speakers into the microphone usually produces poor results, takes as long as the recording itself, and gives you no timestamps or speaker labels.

Method 3: Transcribe in Microsoft Word

Word for the web includes a Transcribe feature for Microsoft 365 subscribers. You can upload an audio file and Word inserts the transcript into your document, with speakers and timestamps.

Good for: people who already have Microsoft 365 and work in Word.

Limits: it requires a paid Microsoft 365 plan, it is only available in Word for the web, and uploads have a monthly time limit. Check Microsoft's Transcribe your recordings page for the current limits and supported languages.

Method 4: Upload the file to an online transcription tool

When you already have a recording, an online tool is usually the fastest route. Here is how it works in FastScribe's audio to text converter:

1. Upload the file. MP3, M4A, WAV, AMR, and video files such as MP4 or MOV all work, up to 1 GB.
2. Choose the spoken language. There are 105 options. Picking the right one matters more than any other setting.
3. Review the transcript. It opens in an editor with speaker labels and a time range on each sentence. Fix names, numbers, and technical terms.
4. Download the format you need. TXT for plain text, DOCX for Word, XLSX for a spreadsheet, or SRT for subtitles.

You can try 15 minutes as a guest without creating an account, and signing up gives you 120 free credits.

Good for: interviews, meetings, lectures, podcasts, voicemails, and anything longer than a few minutes.

Limits: like every automatic tool, accuracy drops with background music, heavy noise, or several people talking over each other, so always check the important parts.

Which output format should you choose?

• TXT if you just want to read, search, or paste the text somewhere.
• DOCX if you are writing an article, report, or meeting notes in Word or Google Docs.
• XLSX if you want to sort, filter, or log what was said, for example when reviewing footage.
• SRT if the text is going back onto a video as captions. See Video to SRT for how to add the file to YouTube, Premiere Pro, CapCut, or VLC.

Tips for a more accurate transcript

1. Record close to the speaker. Distance and room echo cause more errors than file quality or bitrate.
2. Avoid background music when you can. Speech under music is the hardest case for any transcription tool.
3. Choose the correct language before you start, especially for accents or mixed-language recordings.
4. Upload the original file instead of a re-recording or a heavily compressed copy.
5. Check names and numbers against the audio. These are the details automatic transcription most often gets wrong.

Common situations

• A voicemail you need in writing: save it from your phone first. Voicemail to Text shows how on iPhone, Android, and Google Voice.
• An MP3 song or podcast: use MP3 to Text. Songs with clear vocals give a usable lyric draft.
• A meeting recording: see How to Turn a Meeting Recording Into Clear Notes.
• A lecture: see How to Turn a Lecture Recording Into Study Notes.

Summary

If you are recording right now, your phone's recorder or Google Docs voice typing can be enough. If you already have a file, Word works for Microsoft 365 users, and an online tool such as FastScribe handles any common format, gives you speaker labels and timestamps, and exports TXT, DOCX, XLSX, or SRT.
