The Solution

One voice engine for
every identity decision.

Deepfake detection, voice authentication, voice MFA and watchlist screening share a single voiceprint model — so the same voice protects a phone call, a mobile app and a payment. API-first, and deployable in the cloud, on-premise or on-device.

CAPABILITY 01

Voice authentication

Confirm a caller's identity from a few seconds of natural, text-independent speech. No passphrase, no security questions — and language-agnostic out of the box.

  • Text-independent & language-agnostic
  • Active or fully passive enrollment
  • Tunable decision thresholds per use case

01 · CAPTURE

Any channel

Telephony, IVR, mobile app, web and messaging.

02 · EXTRACT

Voiceprint

Irreversible 512-d template; raw audio optional to retain.

03 · ASSESS

Liveness

Replay & synthetic-speech scored independently.

04 · MATCH

1:1 / 1:N

Verify a claim or search a database in seconds.

05 · DECIDE

Decision

Verify, challenge or block — returned in milliseconds.

CAPABILITY 02

Watchlist & fraud screening

Screen inbound voices against a federated watchlist of known fraudsters, with N:M checks that catch one voice enrolled under many identities.

  • Blacklist, whitelist and N:M duplicate detection
  • Ranked matches with confidence scores
  • Real-time alerting on inbound audio

01 · EXTRACT

Voiceprint

Inbound audio reduced to an irreversible template.

02 · SEARCH

N:M match

Compared against the federated fraudster gallery and duplicate enrolments.

03 · ALERT

Ranked hits

Surfaces ranked candidates with confidence scores, in real time.

CAPABILITY 03

Deepfake & liveness detection

A dedicated layer — separate from the biometric match — rejects recordings, replays and generative-AI speech before they ever reach an agent, IVR or app.

  • Passive & active liveness
  • Deepfake / voice-clone classifiers
  • Replay and channel-tamper detection

live speaker — pass
01 · PROBE

Signal scan

Multi-dimensional analysis of the raw audio, separate from the biometric match.

02 · CLASSIFY

Spoof models

Replay, synthetic-TTS, voice-clone and splice classifiers score the sample.

03 · GATE

Pass or block

Genuine speech passes; spoofed audio is rejected before it reaches you.

CAPABILITY 04

Voice MFA & transaction signing

A digit-based one-time passcode, spoken by the user, binds approval to a specific transaction — stronger than an SMS OTP and built for true non-repudiation.

  • Cryptographic one-time digits
  • Irrevocably bound to the transaction
  • Phishing- and replay-resistant

Voice + codeMatch
transaction signed
01 · ISSUE

One-time digits

A cryptographic OTP is generated for this exact transaction.

02 · SPEAK

Voiced back

The user reads the digits aloud.

03 · VERIFY

Voice + code

The voiceprint and the spoken digits are checked together.

04 · SIGN

Bound approval

Approval is cryptographically bound to the transaction — non-repudiable.

CAPABILITY 05

Continuous authentication

Passively monitor identity across an entire live interaction to catch mid-call handovers, social-engineering and account-takeover the moment they happen.

  • Per-utterance re-scoring
  • Mid-session speaker-change alerts
  • Streaming-API friendly

01 · RESCORE

Every utterance

Identity is re-scored passively across the entire live session.

02 · ALERT

Drift caught

A mid-call handover or takeover triggers an instant alert.

Security & compliance

Privacy by design.

Voiceprints are mathematical templates that contain no personally identifiable information — and the underlying ValidSoft technology holds multiple EU privacy seals.

No PII

Voiceprints are mathematical — they can't be reversed into a recording.

Privacy seals

Multiple EuroPriSe EU privacy seals on the core technology.

Global compliance

Aligned to GDPR, CCPA, HIPAA and BIPA.

Flexible deployment

Cloud SaaS, on-premise or on-device — your choice.

Accuracy

Benchmarked where it counts.

Independent, NIST-style evaluation across clean, telephone and noisy conditions, plus adversarial deepfake and replay attacks. Vpronix is tuned for the hard cases — short utterances, cross-channel audio and generative-AI spoofing.

Clean studio audio99.4%
Telephone channel98.7%
Noisy field recording96.1%
Synthetic-speech rejection99.0%

Deepfake-aware

Patented detection of synthetic, cloned and replayed speech flags AI-generated voices before they ever reach an agent, IVR or app.

Frictionless

Passive, text-independent authentication verifies customers from natural speech — no passphrases, PINs or security questions.

Privacy-first

Voiceprints are mathematical and contain no PII — backed by EU privacy seals and aligned to GDPR, CCPA, HIPAA and BIPA.
