It’s an interesting idea, but once the project begins to expand outside of the English & Spanish (and non-European language ) communities this system will run into problems. A number of non-European language speakers are often incapable of pronouncing certain letters, letter combinations, etc, quite simply because those sounds and letters don’t exist in their language. If we were to have a Russian juror judging the pronunciation of a Japanese applicant, there is A LOT of room for misinterpretation.
Of course the same issue exists with the current system too…
Rather than word phrases, why not a randomly generated number string? There is still a slight issue with pronunciation but this is limiting the number of possibilities down to 1 through to 9, rather than an entire language of phrases & words?
Edit: This would make it easier at a later point when we need language specific jurors, all they would need to do is know the number 1 - 9 in the target language. I’d argue many people know how to count to 10 in more than one language, but can’t actually speak the language itself, so a juror could in theory be used for multiple cases.
Randomly generated QR code + a short number phrase given during initial registration
User prints / shows QR code & number phrase, reading the number phrase out (number phrase could be replaced with simple hand gesture pictographs for Deaf / Mute communities)
Juror verifies QR code & number (or hand gesture)
