How to transcribe a voice memo on iPhone
A voice memo is just an audio file on your phone. Transcribing it means running speech recognition over that audio to get text you can search, paste and edit. On an iPhone this can happen entirely on the device: Kaseta transcribes in 99 languages without an account, without a server, and with the network switched off.
One thing to clear up first, because the search results are full of it: this is an app, not a gadget. A lot of what sells as a “voice recorder with transcription” is hardware — a pocket dictaphone with a subscription bolted on. Kaseta is software on the phone already in your pocket. Nothing to buy, nothing to charge, nothing to pair.
What you already have
Voice Memos saves every recording as an .m4a file on the phone, which is why it can be handed to another app instantly instead of being uploaded first. If the file came from somewhere else — an email attachment, a message, a download — the route is the same, and the .m4a guide walks through it.
What it costs
The free plan records without limits and transcribes up to 5 minutes of each recording. Audio keeps recording past that point and waits; the cap is on transcription, never on the recording. Pro — €19.99 a year, or €39.99 once and never again — lifts the cap to 3 hours per recording, adds a higher-accuracy mode, and turns on file export with timestamps.
When something else is the better tool
- Apple’s own transcripts. iOS 18 added them to Voice Memos. If your language is one Apple covers and you only need the occasional short transcript, you already have this, it is free, and you do not need another app.
- Otter, Notta and the other cloud services. They run a bot that joins your Zoom call, label who said what, and keep a searchable archive your whole team can open in a browser. Kaseta does none of that. If that workflow is the job, they are better at it and worth their subscription.
- A desktop and a large archive. If you have two hundred hours of interviews on a Mac, running a local Whisper build there will chew through them faster than any phone. That is also offline, and it is free.
- A human transcriptionist. For a legal deposition or anything that has to be verbatim and certified, no automatic transcript of any kind is the right answer.
Kaseta earns its place in one specific case: the audio should stay on the device, and you would rather not rent access to your own recordings by the minute. If that is you, start from the homepage or open a memo in the app.
