How do I use Modulate Velma to monitor AI voice agents for unsafe or non-compliant behavior?

Modulate12 min read

Most teams deploying AI voice agents worry about what happens when those agents go off-script, mishandle sensitive topics, or drift into behavior that violates policy. Modulate Velma is designed to solve exactly this problem by monitoring AI voice agents in real time, detecting unsafe or non-compliant behavior, and giving you actionable controls to respond quickly.

This guide explains how to use Modulate Velma end-to-end: from setup and integration to defining policies, reviewing incidents, and building a scalable compliance workflow.


What is Modulate Velma and why use it for AI voice agents?

Modulate Velma is a safety and compliance layer for voice interactions. Instead of trusting your voice AI to “behave,” you route its audio through Velma so it can:

  • Analyze conversations in real time
  • Detect harmful, risky, or non-compliant content
  • Flag and score incidents with context
  • Trigger downstream actions (e.g., mute, escalate, terminate, or log)

For customer support, in-game voice, social audio, or sales calls, Velma helps you:

  • Protect users from harassment, hate, or abuse
  • Meet regulatory and internal compliance requirements
  • Maintain brand safety and trust at scale
  • Get visibility into what your voice agents actually say

Core capabilities relevant to unsafe or non-compliant behavior

When planning how to use Modulate Velma to monitor AI voice agents, it’s helpful to understand its main capabilities:

1. Real-time voice analysis

  • Ingests live or near-real-time audio streams
  • Detects problematic content based on acoustic and linguistic signals
  • Supports continuous monitoring of both sides of a conversation (agent and user)

2. Policy- and category-based safety detection

Velma typically supports detection across categories such as:

  • Hate, harassment, and bullying
  • Threats and self-harm
  • Sexual content and exploitation
  • Fraud, scams, and financial abuse
  • Extremism and radicalization
  • Sensitive personal data and privacy violations
  • Custom business-specific compliance violations (e.g., restricted medical claims, prohibited financial advice, or restricted topics for minors)

Each category can be tuned by severity level and mapped to your internal policies.

3. Configurable risk thresholds and actions

You can configure:

  • Detection thresholds: what counts as a violation vs warning
  • Actions: log-only, flag for review, mute the agent, end the session, or escalate to a human
  • Notifications: alerts in dashboards, webhooks, or external tooling (Slack, PagerDuty, etc.)

4. Detailed incident logs and transcripts

Velma maintains:

  • Timestamped transcripts and snippets of audio
  • Categorization and severity scores
  • Policy labels (which policy was violated)
  • Context around the utterance (preceding and following dialogue)

This is critical for audits, training improvements, and root-cause analysis.


Step 1: Set up Modulate Velma for your environment

Before you can monitor AI voice agents, you need to connect your audio pipeline to Velma.

1. Choose your integration mode

Common integration patterns:

  • Server-side audio routing (recommended for production)

    • Your voice agent runs on the backend (e.g., cloud telephony, WebRTC server, or game server).
    • You stream the agent’s audio (and optionally user audio) to Velma via its API or SDK.
    • Velma processes and returns structured safety events in real time.
  • Client SDK integration (for in-app voice)

    • Use a client SDK (e.g., Unity, mobile, web) where available.
    • The client captures audio from the session and sends it to Velma directly, while your logic handles actions based on Velma’s responses.
  • Batch/offline monitoring (for QA and audits)

    • Export recorded calls or sessions.
    • Submit them to Velma for asynchronous analysis.
    • Use this for historical audits, model evaluation, or training data checks.

2. Configure authentication and API keys

  • Obtain API keys from your Velma console or onboarding team.
  • Store keys securely (e.g., environment variables, secret manager).
  • Implement secure transport (HTTPS/TLS) for all audio and event traffic.

3. Decide what audio to send

For AI voice agent monitoring, best practices include:

  • Monitor both directions: send both the agent’s and the user’s audio. This lets you see whether the agent is responding inappropriately to provocation or unsafe user content.
  • Include metadata:
    • Session ID or conversation ID
    • Agent identifier (model, version, persona)
    • Channel (phone, game, in-app, web)
    • User region or regulatory context (where allowed and compliant)

Metadata enables more precise reporting and policy targeting.


Step 2: Define what “unsafe” and “non-compliant” mean for your use case

Modulate Velma’s power comes from aligning detection with your specific policies. Start by defining:

1. Safety policies (user protection)

Common safety policies for AI voice agents:

  • No hate or harassment
    • Agent must not use slurs, derogatory language, or personal attacks—even if the user does.
  • No explicit sexual content
    • Agent avoids sexual roleplay, explicit descriptions, or content inappropriate for minors.
  • No threats or encouragement of self-harm
    • Agent must never threaten users or provide instructions for self-harm or violence.
  • No bullying or targeting minors
    • If your platform is youth-oriented, stricter rules on tone, content, and topics.

2. Compliance policies (regulation and internal rules)

Depending on your domain:

  • Financial services

    • No unapproved investment advice
    • No guaranteed-return claims
    • No solicitation that violates local securities or consumer-protection laws
  • Healthcare and wellness

    • No diagnosis or treatment recommendations beyond approved scripts
    • No promises of cures
    • Strict handling of health-related personal data
  • E-commerce and customer support

    • No misleading claims about refunds, warranties, or product capabilities
    • Adherence to scripted disclosures and disclaimers
  • Youth and education

    • Restricted topics for minors
    • Age-appropriate language and content

Document these rules in human-readable form first. Then map them to Velma’s categories and labels.


Step 3: Configure Velma’s safety and compliance rules

Once your policies are clear, translate them into Velma configuration.

1. Select and tune categories

Within your Velma dashboard or configuration files:

  • Enable relevant categories
    • Hate/harassment, sexual content, self-harm, etc.
  • Set severity thresholds
    • Example:
      • Mild profanity: log only
      • Targeted harassment: immediate flag and high severity
  • Choose your tolerance
    • For kid-focused apps, set very low tolerance for profanity or adult topics.
    • For adult gaming or social spaces, allow mild profanity but still block hate or threats.

2. Define actions per rule

For each category and severity level, specify:

  • Monitor only

    • Just log and surface in reports; no real-time interruption.
  • Soft intervention

    • Mute agent temporarily
    • Have the agent respond with a safe fallback message
    • Add a UI warning or safety banner in the session
  • Hard intervention

    • Terminate the session
    • Hand off to a human agent
    • Block further responses from the AI

Map these actions to your risk appetite and regulatory obligations.

3. Add custom or domain-specific rules

If Velma supports custom classifiers, keyword lists, or pattern-based rules, use them to capture:

  • Forbidden phrases (e.g., “I guarantee you’ll double your money”)
  • Required disclaimers that must appear under certain conditions
  • Restricted topics (e.g., specific medical or legal advice)

Test custom rules in a sandbox environment before enabling them in production.


Step 4: Connect Velma’s outputs to your AI voice agent behavior

Monitoring alone is not enough; you need a loop between Velma’s insights and your agent’s responses.

1. Real-time enforcement loop

Architect your system so that:

  1. Your AI voice agent generates a response (text or audio).
  2. Before (or as) it is rendered to the user, the audio stream is sent to Velma.
  3. Velma returns safety/compliance events with categories, severity, and confidence scores.
  4. Your orchestration logic decides:
    • Deliver as-is
    • Modify or filter the response
    • Replace with a safety fallback
    • Escalate to a human or terminate

Where possible, design this loop to operate within your latency budget (e.g., sub-second for live conversations).

2. Fallback and recovery strategies

To handle unsafe or non-compliant outputs, configure your agent to:

  • Use safe response templates
    • “I’m not able to discuss that topic, but I can help with…”
  • Redirect to information pages or human assistance
    • “This question is better handled by a human representative. Let me transfer you.”
  • Apologize and correct
    • If an unsafe response is detected after the fact, follow up with a corrective, policy-compliant message.

3. Handling user-generated unsafe content

Modulate Velma can also detect when users say or request something unsafe. Decide how your agent should behave when users:

  • Harass or use hate speech
  • Ask for illegal instructions
  • Discuss self-harm or distress

Combine Velma’s detection with AI behavior policies like:

  • De-escalation responses
  • Crisis resource information (for self-harm scenarios, where appropriate)
  • Warning or blocking mechanisms for repeat offenders

Step 5: Use Velma’s dashboards and logs for ongoing monitoring

Real-time interventions handle immediate risk, but long-term safety and compliance depend on solid monitoring.

1. Review incident dashboards

In your Velma interface, regularly review:

  • Total incidents over time (daily, weekly, monthly)
  • Breakdown by category and severity
  • Top agent models or versions associated with violations
  • Top channels or geographies where incidents occur (subject to privacy and consent)

Use this to identify patterns and high-risk areas.

2. Dive into transcripts and audio snippets

For flagged sessions:

  • Review the full conversation and timestamps
  • Determine whether the agent or user triggered the flag
  • Assess whether your thresholds are too strict or too lenient
  • Identify specific prompts or user behaviors that trigger unsafe responses

Feed this analysis back into both your safety configuration and your model training or prompt design.

3. Build reports for compliance and leadership

Create periodic reports that summarize:

  • Number and type of violations
  • How quickly incidents were detected and handled
  • Trends before and after policy changes or model updates
  • Evidence of compliance with regulatory and internal standards

Velma’s structured logs simplify compliance audits and internal reviews.


Step 6: Create a feedback loop into your AI models and prompts

Monitoring is most effective when it feeds continuous improvement.

1. Use incidents as training data

Label incidents as:

  • True positive (correctly flagged)
  • False positive (safe but flagged)
  • False negative (unsafe behavior not caught by Velma, detected later through other means)

Then:

  • Use true positives to fine-tune your AI voice agent or update safety prompts
  • Use false positives to adjust Velma thresholds and reduce noise
  • Use false negatives to refine both Velma configuration and AI safeguards

2. Harden prompts and guardrails

For LLM-based or generative voice agents:

  • Add explicit safety instructions in system prompts (e.g., topics, tone, forbidden behavior)
  • Use tool calls or middleware to enforce rules before text is synthesized to audio
  • Limit the agent’s ability to generate content outside its domain of expertise

Test these updates by running synthetic conversations through Velma’s monitoring.


Step 7: Align Modulate Velma with privacy, consent, and legal requirements

Monitoring AI voice agents involves processing user audio, which has privacy implications.

1. Ensure you have necessary user consent

  • Clearly disclose voice monitoring in your terms and privacy notices
  • For sensitive contexts or jurisdictions with strict rules (e.g., two-party consent), ensure recording and analysis practices comply with local law
  • Provide clear options or alternatives where required

2. Configure data retention policies

Work with Velma and your legal team to:

  • Define how long audio and transcripts are stored
  • Determine anonymization or pseudonymization strategies
  • Limit access to sensitive data via role-based access control

3. Segment data by region and regulation

If you operate in multiple regions (e.g., EU vs US vs other markets):

  • Tag sessions with region metadata
  • Apply region-specific policies or stricter rules where required
  • Maintain audit trails for region-specific regulatory compliance

  • Integration: Call recording platform streams calls to Velma and to the coach.
  • Policies:
    • No unapproved financial promises
    • No discriminatory language
  • Actions:
    • AI coach prompts the human rep when they are close to making a non-compliant statement
    • High-risk flags trigger a post-call compliance review
  • Monitoring:
    • Compliance team reviews flagged calls and maintains certification logs

Best practices for using Modulate Velma to monitor AI voice agents

To get the most out of Modulate Velma for unsafe or non-compliant behavior monitoring, keep these practices in mind:

  1. Start with clear, written policies
    Translate your legal and safety policies into concrete examples and rules before configuring Velma.

  2. Pilot before full rollout
    Run Velma in “shadow mode” at first: log incidents without taking action. Use this to calibrate thresholds and minimize false positives.

  3. Combine Velma with model-level safeguards
    Don’t rely solely on post-hoc monitoring. Use Velma alongside prompt engineering, model filters, and rule-based checks.

  4. Build a defined incident response playbook
    Decide who reviews incidents, how they’re escalated, and what corrective steps follow. Document this process.

  5. Continuously review and iterate
    As your AI voice agents evolve, regularly revisit Velma’s configuration, your policies, and your dashboards.

  6. Respect user privacy and transparency
    Be explicit that voice interactions may be monitored for safety and compliance, and implement strong data protection practices.
