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.

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.

Always confirm current tiers on the vendor's own pricing page before committing. Verbatim vs cleaned mode and GDPR compliance features can also vary by plan tier within a single tool.

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.
