The problem
Accents and dialects are where speech models break.
Speech models are tested on the accents they were trained on. Real users speak in dialect, switch languages mid-sentence and talk in noisy rooms.
Getting that data right takes verified native speakers, consent for every recording and transcribers who know the language, not just the alphabet.
- Narrow accent coverage
- Code-switching left out
- Recordings without clear consent

How vetting works
Every expert comes with the evidence.
Rather than a profile and a score, you get the record behind each person on your project, and you can review it before they start.
- Recorded AI video interview with the full transcript and a scored rubric
- ID and liveness check, with duplicate-account detection
- Credentials checked with the issuing body where the role needs them
- Integrity flags from the interview, shown to you in plain words
- Paid calibration against gold answers before any client work
