for AI agents

Every voice agent needs an identity.

Verifiable identity for the age of AI voice

Enterprises are rapidly deploying AI voice agents to talk to customers, make decisions, and act on their behalf.

But when an AI agent speaks, three fundamental questions remain unanswered:

  1. 01

    Who is this?

    There is no persistent, verifiable identity attached to the voice itself.

    Verda gives every voice agent a verifiable identity tied to the enterprise that authorized it.

  2. 02

    What is it authorized to do?

    An agent may claim to represent your company. But who authorized it? What is it allowed to say or do? Is that authorization still valid?

    Verda cryptographically binds the agent, organization, authorization, and session to its voice.

  3. 03

    Is it compliant?

    Regulators are beginning to require AI-generated audio to carry machine-readable signals that identify it as synthetic or AI-generated.

    Verda provides persistent machine-readable marking designed to support EU AI Act and California AI transparency requirements.

Identity that survives the call.

Traditional identity systems stop at the edge of your infrastructure.

  • API credentials don't travel through a phone call.
  • SIP headers can disappear.
  • Metadata gets stripped.
  • Caller ID can be spoofed.

Verda binds identity to the audio itself.

The identity travels with the agent's voice through telephony networks, codecs, transcoding and re-recording — and can be recovered and verified on the other side.

  1. 01
    Enterprise
  2. 02
    Agent
  3. 03
    Authorization
  4. 04
    Session
  5. 05
    Voice

So a recipient can verify not simply:

“This is AI.”

But:

“This is an authorized AI agent acting on behalf of this organization.”

One infrastructure for identity and compliance

Verda combines enterprise-controlled identity, cryptographic authorization and robust audio watermarking into a single trust layer for AI voice.

  1. 01

    The enterprise controls the identity.

  2. 02

    The agent receives a verifiable credential.

  3. 03

    Each interaction can be bound to an agent and session.

  4. 04

    Verda embeds that identity into the generated speech.

  5. 05

    The identity survives the telephony stack.

  6. 06

    The recipient can detect and verify it.

The identity belongs to you — not your model vendor, carrier or voice provider.

Built on state-of-the-art audio technology

Identity infrastructure only works if the identity survives the real world.

Up to 256 bits

Data capacity

Embed rich identifiers and cryptographic references directly into audio — with up to 256 bits of payload capacity.

Enough capacity for agent, organization, deployment and session-level identity architectures.

Built to survive telephony

Verda's watermark is engineered to persist through real communication channels, including:

  • PSTN
  • VoIP
  • cellular networks
  • telephony codecs
  • transcoding
  • compression
  • re-recording

The identity stays with the voice after it leaves your infrastructure.

Best-in-class perceptual quality

Authentication should not make an AI agent sound worse.

Verda is designed for high-fidelity, imperceptible watermarking, preserving natural speech while carrying persistent machine-readable identity.

Built by audio experts

World class team with researchers from MIT, Stanford and IIT.

Our team brings 15+ years of experience in audio, signal processing and machine learning.

Verda's technology is built specifically for the difficult intersection of audio quality, robustness, data capacity and real-world transmission.

Compliance built into the infrastructure

Identity solves the trust problem.

Machine-readable provenance helps solve the compliance problem.

Verda is designed to help organizations and AI providers address emerging transparency requirements, including:

EU AI Act

Article 50(2) requires synthetic audio to be machine-readably marked and detectable as artificially generated — that is the duty Verda handles. Article 50(1) separately requires that a person be told they are talking to an AI; that is a deployer duty Verda does not replace.

California AI Transparency Act

California establishes latent disclosure requirements for covered generative-AI providers, including provenance information and unique identifiers for generated audio.

Verda lets the same infrastructure support both agent authentication and regulatory provenance.

No separate compliance watermark.No separate agent-identity layer.

One signal. One identity infrastructure.

From AI disclosure to AI trust

Most watermarking systems answer:

“Was this generated by AI?”

Verda goes further:

  • Who created this voice?
  • Which organization authorized the agent?
  • Which agent is speaking?
  • What is it authorized to do?
  • Which interaction did this come from?
  • Is the credential still valid?

That is the difference between identifying AI content and establishing trust in an AI agent.

Give every agent an identity that travels with its voice.

Verda is the identity and trust layer for AI agents.

  • Cryptographically bound.
  • Enterprise controlled.
  • Built for telephony.
  • Designed for compliance.
