Figuring out how to transcribe a conversation comes down to one question: where is the conversation happening? A live chat across the table needs a real-time captioning app. A phone call needs call recording. A conversation you already recorded needs a transcription pass. And a conversation that’s already published online — a podcast episode or a video interview — can be pasted straight into a URL-based tool.

Most guides pretend one app does all of this. It doesn’t. Here’s the honest breakdown for each situation, with the free native options first.

The short version

  1. In-person, live (Android): open Google’s free Live Transcribe app, set the phone between speakers, and read the text as it appears.
  2. In-person, live (iPhone): use a real-time notes app like Otter or Speakwise, or record with Voice Memos and transcribe after.
  3. Phone call (iPhone, iOS 18.1+): tap Record in the Phone app — it saves audio and a transcript to Notes automatically.
  4. Phone call (Android): use a call-recording app (Cube ACR, Otter), then transcribe the recording.
  5. Already recorded (a file): run it through a transcription app that accepts audio files.
  6. Already published online (podcast/video of the conversation): paste the URL into TranscriptMagic for a clean, timestamped transcript.

Transcribing an in-person conversation as it happens

If two or more people are talking in the same room and you want live text, you need a real-time captioning tool — not a transcription service that works from a finished file.

On Android, Google’s Live Transcribe is the standard. It’s completely free, supports 70+ languages, and shows words on screen almost instantly. Google built it with Gallaudet University for the deaf and hard-of-hearing community, so it’s genuinely good at continuous speech. The one catch: it’s designed for live display. By default it doesn’t record audio or keep a permanent transcript — you’re reading in the moment. If you turn on the optional history setting, it can save a transcript for a short window (roughly three days) so you can scroll back, but it’s not built to be a long-term archive.

On iPhone, there’s no built-in equivalent for room conversations, so people reach for apps like Otter.ai (great for meetings, adds speaker labels, and keeps a searchable transcript) or newer iOS-native voice-notes apps. If you don’t need it live, the simplest free route is to open Voice Memos, hit record, and let it transcribe afterward — recent iOS versions generate a transcript right inside the app.

A few things that dramatically change accuracy for in-person capture:

  • Get the mic close. Set the phone within a couple of feet of whoever’s talking. Distance and background noise are the number-one killers of accuracy.
  • One person at a time. Automatic transcription struggles badly with crosstalk. If two people talk over each other, expect garbled lines.
  • Quiet room wins. A café with music will drop your accuracy from ~95% to something you’ll spend an hour fixing.

Transcribing a phone call

This is where the platform matters most.

On iPhone, since iOS 18.1, Apple bakes this in. During a call, tap the Record button in the top-left of the Phone app. Everyone on the call hears an automated announcement that recording has started (that’s a legal feature, not a bug). When the call ends, iOS drops both the audio and a full text transcript into the Notes app under a “Call Recordings” folder. No third-party app, no subscription. Availability still depends on your country and language, so check if you don’t see the button.

On Android, there’s no reliable native call-recording-plus-transcription in most regions — Live Transcribe shows text live but won’t save the call. The practical route is a dedicated call-recording app (Cube ACR is a common pick, or Otter for business calls), then transcribe the saved recording. One honest caveat: on Android 10 and later, the OS restricts access to call audio, so these apps frequently fail to capture the other party — reliability varies a lot by phone brand and Android version. Test with a throwaway call before you rely on it for anything important.

Before you record any call, know your consent rules. In the U.S., some states are “one-party consent” (you can record a call you’re part of) and others are “all-party consent” (everyone must agree). Internationally it varies more. When in doubt, say “I’m recording this call” out loud at the start — it’s both the legal-safe move and just decent.

Transcribing a conversation you already recorded

If the conversation is done and you’re holding a file — a voice memo, a Zoom export, a raw interview recording — you don’t need anything live. You need a transcription pass on that audio.

The fastest free options: Voice Memos on iPhone transcribes recordings in-app. Otter, and most speech-to-text apps, let you import an audio file and get text back in minutes. For a formal sit-down interview, the workflow that most tools skip is the cleanup — adding speaker labels, fixing crosstalk, and exporting to a format you can actually edit — so budget time for that pass rather than trusting the raw output.

Or transcribe the file directly (Plus & Pro). TranscriptMagic is primarily a URL transcriber, but if your conversation lives as an mp3 or m4a on your device and you’d rather not install anything, signed-in Plus and Pro users can upload it straight to /upload/ — audio or video, up to 500MB / 6 hours — and get an AI transcript back. It’s a paid feature (10 credits per hour of audio), so the free native options above stay the no-cost path; the upload is there when you want a clean, exportable transcript in one step.

When the conversation is already online

Here’s the one case where TranscriptMagic is the fastest possible route. If the “conversation” is a published podcast episode, a YouTube interview, or a video conversation posted on TikTok, Instagram, X, or LinkedIn, you don’t need to record anything — the audio already exists at a public URL.

Paste that link into TranscriptMagic and it runs AI speech-to-text, returning a clean, timestamped transcript you can export as TXT or PDF. It works for a Spotify or Apple Podcasts episode, or any YouTube video. That’s the whole trick: if there’s a public URL on a supported platform, paste it. If it’s a private file on your phone, use the free native tools above — or, on a paid Plus/Pro plan, upload the file directly.

Common questions

How do I transcribe a conversation for free?

For live in-person conversations on Android, Google Live Transcribe is fully free. On iPhone, Voice Memos transcribes recordings at no cost, and iOS 18.1+ transcribes phone calls for free straight into Notes. For a conversation already posted online, TranscriptMagic gives you free credits to transcribe from a URL.

What’s the best app to transcribe a conversation in real time?

On Android, Live Transcribe is the best free real-time option. On iPhone and for meetings with multiple speakers, Otter.ai is the common pick because it labels speakers and keeps a searchable transcript. Choose based on whether you need it live on screen or saved for later.

How do I transcribe a phone call?

On iPhone (iOS 18.1 or later), tap Record in the Phone app during the call — the transcript lands in Notes automatically. On Android, record with an app like Cube ACR, then transcribe the saved file — though on Android 10+ these apps often can’t capture the other party, so test first. Always announce that you’re recording to stay on the right side of consent laws.

Can I transcribe a conversation without recording it?

Yes, if you use a live-captioning app like Live Transcribe that displays text as people speak. The trade-off is that most live tools don’t save the transcript by default, so you’re reading in the moment rather than keeping a copy. If you want an archive, record first and transcribe after.

It depends on where you are. Many U.S. states require only one party to consent; others require everyone. Other countries have their own rules. The safe universal move is to tell the other people you’re recording before you start.

Can TranscriptMagic transcribe a live or recorded conversation from my phone?

It can’t capture a live conversation — there’s no microphone-listening mode. For a recorded audio file, though, paid Plus and Pro users can upload it directly at /upload/ (up to 500MB / 6 hours, 10 credits per audio-hour) and get an AI transcript. Otherwise, TranscriptMagic works from a URL — the fastest route when the conversation is already published online as a podcast or video. For a free option on a private recording, the native apps above are the way to go.

The bottom line

Match the tool to the situation: Live Transcribe or Voice Memos for in-person, the built-in Phone app recorder for calls on iOS, and a file-based transcriber for recordings you already have. And when the conversation is already sitting online as a podcast or video, skip the recording entirely — paste the link into TranscriptMagic and get a clean, timestamped transcript in a couple of minutes.
