Read the code back by voice

Press Start listening, allow the microphone, then read the code aloud — just say the characters, letter by letter and digit by digit (e.g. “K, Q, 4, …”). The NATO phonetic alphabet (“Kilo, Quebec, Four”) works too. Press Submit read-back; New code gives you a fresh random code. Voice only — the box isn't keyboard-editable.
