Turning a meeting, an interview or a WhatsApp voice note into text no longer requires a paid app. Most everyday tools already transcribe in Spanish, yet each one stores the resulting text in a different place and alerts other participants — or fails to — in its own way. Spanish law draws a clear line between transcribing a conversation you take part in for your own use and doing so inside a company, where data protection rules come into play. The details below reflect official documentation as of 31 October 2026.
This article focuses on transcription: converting speech into text and, in some cases, summarising it with AI. Recording phone calls is a separate matter.
Built-in transcription options and language support
What you can use depends on where the conversation happens. These are the features included by default in the most common platforms:
- Microsoft Teams. Live transcription displays text in real time with each speaker’s name and timestamp, and starts automatically when a meeting is recorded. It supports Spain and Mexican Spanish, plus Catalan. Afterwards, organisers and co-organisers can download the transcript as a .docx or .vtt file. Live translation is a paid feature within Teams Premium.
- Google Meet. Transcripts are enabled from the meeting’s Tools menu, only on desktop or Android, and are saved to the organiser’s Google Drive. They support Spanish and, as of October 2026, are limited to Workspace editions such as Business Standard, Business Plus, Enterprise or Workspace Individual, enabled by default except on Education student licences.
- Zoom. Audio transcription is generated from cloud recordings, delivered as a VTT file and, as of October 2026, requires a Pro, Business, Education or Enterprise account. It defaults to English, but the language can be changed — Spanish is on the list — and the transcript regenerated.
- WhatsApp. Voice message transcripts are off by default and, on Android, currently work only in English, Portuguese, Spanish and Russian (on iPhone the list depends on the iOS version). They are enabled under Settings > Chats > Voice message transcripts.
- iPhone. The Voice Memos app transcribes while recording or afterwards on iPhone 12 or later, with Spanish included. Apple Intelligence can summarise that transcript.
- Pixel. Google’s Recorder app transcribes in real time in Spain and US Spanish, among other languages. AI summaries, however, are available only on Pixel 8 and later and in seven languages, none of which is Spanish.
-
Samsung Galaxy.
Transcript Assist transcribes and summarises recordings from the voice recorder, calls, Samsung Notes or the interpreter, in 22 languages including Spanish, according to the Galaxy AI page. Audio must be shorter than 3 hours.
For anyone unable to listen to an audio file, these features also serve as accessibility tools, much like other AI apps that describe the world, add subtitles and read aloud for you.
Where the audio ends up and who can see the text
Three models exist.
On the phone itself. WhatsApp states that transcripts are generated on your device and that personal voice messages remain protected by end-to-end encryption: no one outside the chat, not even WhatsApp, can see the transcript content. Only the recipient of the audio sees it; the sender does not.
In the manufacturer’s cloud. Samsung requires a network connection and a Samsung account to transcribe and summarise. Google explains that Pixel Recorder summaries run in an isolated cloud environment.
In the organisation’s account. In Meet, the transcript goes to the organiser’s Drive and is attached to the calendar event, accessible to guests from their organisation. In Teams it stays with the meeting event. Here the text is no longer yours: it is managed by whoever organises the meeting and by the policies the administrator sets.
My reading: a transcript is far easier to copy, search and forward than an audio file. Before enabling transcription, it is worth knowing which account that text will live in, because that is where people will look when they want to recall exactly what was said.
Is it legal to transcribe other people in Spain?
If you take part in the conversation and do it for yourself, the recording itself does not breach the secrecy of communications. Spain’s Constitutional Court established this in ruling 114/1984 of 29 November: someone who records a conversation between others infringes that right, but someone who records a conversation with another person does not, for that reason alone, act contrary to the Constitution.
The same ruling sets the limit: what is done with the recording afterwards, especially its dissemination, may affect other rights such as privacy. Transcribing turns that recording into a document, so the logic extends: the problem is rarely having the text, but what you do with it.
In the personal sphere, the General Data Protection Regulation does not apply to what a natural person does in the course of purely personal or household activities (Article 2.2.c). Transcribing your own voice notes for personal reference fits there.
In a company, things change. Transcribing a work meeting means processing the personal data of attendees, and the controller needs a legal basis (Article 6) and must inform data subjects about who processes their data, for what purpose and on what basis at the time of collection (Article 13). Consent is one possible basis, not the only one, which is why you will not always be asked for it.
The tools already build in part of that notice. In Teams, all participants see a notification that the meeting is being transcribed and can hide their identity in captions and transcripts. In Meet, an icon appears for everyone, and the administrator can require each participant to give explicit consent before transcription, although that setting is off by default.
The contrast with phone calls is striking: Apple states that iPhone call recording, with an audible notice for both parties, is not available in the European Union. For devices that record third parties unnoticed, we have explained what the law says if smart glasses record you without your knowledge.
Before you hit Transcribe
- Announce it at the start, even if the tool already does. A spoken notice clears up more misunderstandings than an icon in a corner.
- Check where it is stored and who will be able to open it later.
- Review the text before using it. Apple advises checking a transcript’s accuracy because it may not faithfully represent the conversation.
- Trust the summary less than the transcript. A summary chooses what matters, and there the AI may leave out precisely the nuance that counted, just as when it summarises a video or a long PDF.
Automatic transcription is among the most useful and least debated AI features, precisely because it seems harmless. But it turns every meeting into minutes that no one drafted or reviewed, stored in someone else’s account. Spanish law is reasonably clear about recording what you hear; what is less understood is the responsibility of whoever later distributes that text.
