About our work
Testing Methodology
A specification check is not a product test. We keep those two kinds of evidence separate, even when that means publishing fewer conclusions.
What the current site includes
Current product pages are source-backed fact sheets. They describe published specifications, prices, plans, data handling, and known gaps. They are not hands-on reviews and do not receive ratings.
What a future review must record
Before we publish a review, we record the device source, firmware and app versions, test dates, room and noise conditions, microphone distance, number of speakers, recording duration, and the exact method version. We retain the underlying samples and results needed to reproduce the conclusion.
How transcription is checked
A valid transcription test uses fixed reference audio and reports word errors, speaker-label errors, omissions, and representative failure cases. Vendor accuracy claims are identified as vendor claims; they are never presented as our measurements.
Scores require evidence
A score is published only when every scored category has current test evidence and another editor has reviewed the calculation. Missing evidence stays missing; it is not replaced with a neutral score or an estimate.
