Why the choice of transcription tool matters
Not all AI transcription tools are built for the same job. A tool optimised for cleaning up a meeting recording into a readable summary is not necessarily suitable for producing a verbatim, timestamped transcript that could be referenced in a court report or a legal complaint. Multi-speaker accuracy, whether the tool offers a true verbatim mode, and where audio and transcripts are stored all affect whether a given tool is appropriate for a given piece of journalism.
UK journalists recording interviews, court proceedings (where permitted), or press conferences are, in effect, processing personal data under UK GDPR the moment a recognisable voice is captured. Understanding a vendor's data storage location and compliance posture is therefore not just a technical detail — it is part of a journalist's data protection obligations under the Data Protection Act 2018 and the ICO's guidance on UK GDPR.

What are you using it for?
Recommended: Google Recorder
For quick, low-cost interview capture, on-device processing avoids uploading source audio to a third party and costs nothing. Otter's free tier is the best cloud-based fallback if multi-device sync or longer recordings are needed.

GDPR and audio recording: what UK journalists should check
- Where the audio and transcript are stored, and whether the vendor offers a UK/EU data residency option or transfers data outside the UK/EEA under a recognised safeguard.
- Whether the vendor acts as a data processor and will sign a Data Processing Agreement (DPA) if your organisation requires one.
- How long audio and transcripts are retained by default, and whether you can delete them on request.
- Whether interviewees or contributors need to be told a recording is being processed by a third-party AI service, particularly if the tool trains models on customer data by default.
- Special category data risk: interviews touching health, criminal allegations, or similarly sensitive topics may need extra safeguards regardless of which tool is used.
Common mistakes
- Assuming any AI transcript is court-admissible verbatim evidence without checking accuracy and reviewing it manually against the recording.
- Using a cleaned-mode transcript (filler words and false starts removed) as if it were a verbatim record — always check which mode was used.
- Uploading sensitive source interviews to a cloud transcription service without checking its data retention and training-data policies.
- Choosing a tool based on price alone and discovering later that it lacks timestamped export needed for referencing specific moments in a recording.
- Not testing a tool's multi-speaker accuracy on a real, noisy recording before relying on it for an important interview.
