LingoDial

Verified voice

Your voice — provably yours.

Enroll once with a Face ID scan. From then on, the verified badge isn't something the app decides to show — it's granted by the server only after a fresh Face ID unlock, per call. There's no local flag to flip, so it can't be faked.

Listening

Enroll once

One voice. Confirmed at capture.

Enrollment is a short read-aloud that captures the one voice you're allowed to clone: yours. It's tied to your Face ID at capture, so there's no path to upload a recording or impersonate someone else.

Your voiceprint is never exported, never downloadable, and never used to train models — and you can delete it permanently whenever you want.

Per-call gate

Face ID unlocks the badge — or the call just continues.

Choose your cloned voice for a call and LingoDial asks for a fresh Face ID. Pass it, and the server mints a single-use attestation that becomes the verified badge the other person sees.

Fail it, cancel, or skip enrollment and nothing breaks — the call simply falls back to the default voice. Verification never blocks the call.

Verified voice

In your own voice — provably.

A cloned voice is only trustworthy if the other person can be sure it's really yours. Enrolling your voice takes a Face ID scan. Using it on a call takes another. Every cloned-voice call carries a badge minted from a fresh, single-use cryptographic proof of that unlock — so “this is really Alex” isn't a claim, it's something Manuel's phone can check.

The in-app verified-voice badge: Alex Rivera, verified, with a single-use Face ID unlock, a fresh cryptographic proof bound to the device, attested moments ago and replay-proof.
  1. Face ID, every call

    A fresh biometric unlock is required each time your cloned voice goes on the line. Fail it and the call simply continues in the default voice — never blocked.

  2. Only your own voice

    You can enroll exactly one voice: yours, confirmed at capture. There is no path to clone anyone else — no uploads, no impersonation.

  3. Provable, not just claimed

    The badge is derived from a single-use proof tied to that unlock. Forged or replayed requests are rejected on the server before any badge is shown.

  4. Yours to delete

    Remove your voiceprint whenever you want. It is never exported, never downloadable, and never used to train models.

Your voice, and only ever yours.
