Voice Agents
Real-time voice and telephony agents inherit every text-based AI risk, plus failure modes unique to speech: transcription-layer injection, caller impersonation, and irreversible actions taken mid-call.
What can go wrong
Transcription-layer injection
Adversarial speech gets transcribed and passed to the model as instructions, not just content.
Caller impersonation
The agent authenticates callers on voice or self-reported details alone, with no real identity verification.
Irreversible mid-call actions
Transfers, cancellations, or refunds get triggered before verification steps actually complete.
Verification skipped under latency pressure
Real-time response pressure causes the agent to short-circuit checks it would otherwise perform.
Illustrative attack path
This is a representative validation target, not a claim that every customer system exposes the same chain.
What Oxyne tests
How it works
Connect via SIP/telephony trunk or the agent's API. Oxyne runs scripted adversarial calls, judge-scores the resulting transcripts and any tool calls the agent made, and reports findings against the real actions taken — not just risky-sounding dialogue.
Scoped interface
Define supported connection paths, authorized actions, credentials, and prohibited behavior before testing.
Evidence produced
Receive the supporting transcript, explicit success criteria, judge reasoning, validation level, and remediation context.
Applicable workflows
Use recurring AI Security Testing for baseline coverage and a separately scoped AI Red Teaming campaign for deeper analysis.
