Voice Identity Transformation

Every agent, one brand voice, in real time.

Voice Identity Transformation converts an agent’s live voice to one brand voice in transit, without delaying the call.

Story01 / 10

Agents sound different. Callers should not hear it.

Voice Identity Transformation keeps the agent’s own voice private and gives every call the same brand voice, without touching a word.

  1. What transit does

    One voice out, and not a word is changed.

  2. Every voice is different

    Callers hear the agent, not the brand.

  3. One profile in transit

    Every line passes the same plates and engine.

  4. One voice on every call

    Same words, and the agent stays private.

A white cable carries a voice through three plates, slotted, waved and smooth, into a white engine with a dark top and one dial, and on to a caller’s headset resting on a sand-rimmed tile.

Six components, each one timed.

Six components convert a voice, each with its own budget.

  • 01

    Audio feature encoder

    Turns the incoming voice into the features the rest of the engine reads.

    • 512-dimensional acoustic feature vectors

Capabilities03 / 10

Mask, neutralise, smooth. The words never change.

Each capability is shown on the same illustrative scene of one voice in transit, and none of them changes a word the agent says.

Enrolled and protected04 / 10

A brand voice you can prove is yours.

A brand voice is enrolled once and protected from then on.

A reference voice reaches an encrypted identity only after consentVoiceIdentityConsentSigned

Reference session

One session with your own voice talent.

Quality validation

Scored before a voice is built.

Encrypted fingerprint

Encrypted in your perimeter. It never leaves your boundary.

Owner consent

No release, no voice. The owner signs before it is built.

Signed output

Every output is signed. A copy can be told apart.

Version rollback

Every version kept, and restorable.

How it runs05 / 10

What happens to a voice in transit.

Five stages between the agent’s microphone and the caller’s ear, all inside the same runtime the agents run on.

One endpoint, the desk you already have.

Voice Identity Transformation arrives as one endpoint to call.

Drop-in endpoint

One endpoint accepts REST requests.WebSocket carries the live stream.

Contact centre platforms

The existing platform estate stays in place.Each platform bridges to the endpoint.

Live quality monitoring

Naturalness is scored continuously.The live voice is monitored during calls.

Voice comparison

Compare two voices on live traffic.Neither ships before the comparison.

Where it runs07 / 10

Beside the agent, inside your boundary.

Voice Identity Transformation is a service of the same runtime the agents run on, so it deploys on-premises or in your private cloud and the audio stays inside the boundary you chose.

  • On-premises

    Runs on your hardware beside the agents, and no audio leaves the site.

  • Private cloud

    Deployed in your accounts and network, inside the agents’ boundary.

  • No extra pipeline

    One runtime carries the agents and the transformation, with no second hop.

Delivers08 / 10

What one voice changes.

One voice across every channel changes what callers remember.

  • 31% improvement in brand recall against generic TTS

    The same voice on every channel, so callers recognise it.

    production deployments

  • 23% increase in CSAT after deployment

    Callers hear warmth rather than a flat synthetic read.

    production deployments

  • 4.9 out of 5 voice naturalness on the MOS scale

    Prosody is carried across, not flattened into a monotone.

    production deployments

  • 100% brand voice consistency across interactions

    One enrolled voice drives every language and every channel.
