Every material design decision is written to a GSTE-style tamper-evidence hash chain and issued a trust receipt with a trace ID — accountable and revocable. This vertical rides the same governed oToGen backbone as every other: one process, one trust chain, one deploy gate.
Turn a few seconds of speech into a voice that reads any text, in 23 languages — self-hosted, no third-party voice cloud. Each voice is bound to a verifiable consent claim (who agreed, to what, until when) that self-invalidates the moment consent is revoked, expires, or the reference changes — nothing is spoken without a live grant. Every clip carries an imperceptible watermark proving it's synthetic and a GSTE trust receipt proving it's consented.
Optional biometric sign-in confirms you and unlocks your memory — a convenience layered on your password, never a replacement, with a liveness check so a photo or recording can't stand in. Face and palm become number-vectors in your browser (never images); voice is verified by oToGen's own speaker-recognition model, checked once and dropped. Enroll once and it signs you in across every oToGen vertical and Viza product through Viza Account.
