Free AI Voice Agent Audit Online

What is the free AI voice agent audit?

The free AI voice agent audit is a request-based testing service from TestMu AI. You submit the phone number your AI voice agent answers on and the behaviors you want checked, and the audit team places 30 or more simulated calls per behavior and emails you a scored report within two business days.

The form above is a request form, not an in-browser analyzer. Nothing is installed and no code, prompt, or API key changes hands, because the audit runs entirely from the outside against the live number your callers already dial. If you would rather score rollout risk before booking any calls, the AI Agent Risk Scorer runs instantly in your browser.

Why do AI voice agents need testing on real phone calls?

A voice agent that answers a scripted demo perfectly can still fail the calls that pay for it. The failures come from conditions a manual test call rarely reproduces. Here is what real call testing catches:

• Probabilistic failures: An agent can pass the same scenario nine times and fail it on the tenth attempt.
• Telephone audio quality: Narrowband telephony codecs such as ITU-T G.711 sample voice at 8 kHz, far below studio audio.
• Interruptions and barge-in: Real callers talk over the agent, and turn-taking breaks in ways demos never show.
• Off-script probing: Callers ask questions outside the prompt, which is where invented policies and prices surface.
• Escalation gaps: An agent that never hands off looks contained while customers leave unresolved.
• Regression after every change: A prompt rewrite, model swap, or knowledge base update can break behavior that previously passed.

That last point is why teams re-audit rather than test once. For the wider methodology, see the TestMu AI guide to voice agent testing and our review of AI voice agent testing tools.

How to request your free AI voice agent audit?

The request takes about five minutes and is split across three steps in the form above. Follow these steps:

• Enter the report recipient: Add your first name, last name, and work email in step one. The finished audit report is emailed to this address.
• Add your company context: In step two, give your company name, an optional website, your industry, and your monthly call volume so caller goals match your traffic.
• Add the agent number and pick behaviors: In step three, enter the phone number your voice agent answers on with its country code, describe what the agent does, select the behaviors to test, and confirm you are authorized.
• Submit and receive the scored report: Submit the form. A short verification call is placed first, the simulated calls run, human reviewers check the results, and the report arrives within two business days.

Calls are placed sequentially at normal conversation volume, so the audit measures conversation quality and never concurrency. If you want to sanity check the number format before you submit it, the Phone Number Validator checks it against the international ITU-T E.164 numbering plan.

Which voice agent behaviors does the audit test?

The audit covers seven core behaviors, and each one you select is exercised by 30 or more separate simulated calls rather than a single scripted run. These are the behaviors on the form:

• Verify Identity: Does the agent confirm who it is talking to before it shares account details?
• Collect Required Information: Does the agent capture every field it needs, even when answers arrive out of order?
• Confirm Before Acting: Does the agent read details back before it books, changes, or cancels anything?
• Transfer and Escalation: Does the agent hand off to a human at the right moment, with full context?
• Handle Frustrated Callers: Does the agent stay useful when callers interrupt, vent, or push back?
• Catch Hallucinations: Does the agent invent policies, prices, or facts under off-script probing?
• Stay On Topic: Does the agent resist derailment, irrelevant requests, and prompt injection?

An Other field captures behaviors unique to your call flow. For adversarial coverage of a text or tool-using agent, pair the audit with the Agent Red Team Scan, and if you are still choosing a platform, compare options with the AI Agent Comparison tool.

What is inside the AI voice agent audit report?

The report is emailed to the address you enter in step one and is written to be handed straight to the team that owns the agent. It contains three parts:

• Pass or fail scorecard: Every selected behavior with its pass count across the simulated calls.
• Failure transcripts: Timestamped snippets from the worst calls, showing where the conversation broke.
• Prioritized fixes: Concrete recommendations ordered by customer impact, so you know what to fix first.

The table above illustrates the scorecard format with made up numbers. It is not live data and not a result from any real audit. Once the fixes ship, most QA teams fold the same voice scenarios into a regression suite: Kane AI authors those tests in natural language, and the TestMu AI real device cloud of 10,000+ real devices runs them on the same telephone audio path production callers use.

Who should request the AI voice agent audit?

Any team running an AI voice agent that answers a phone number can request the audit, and the simulated caller goals are tuned to the industry you pick on the form. It is most useful in these situations:

• Before a production launch: Establish a behavior baseline before real customers reach the agent.
• After a prompt or model change: Confirm that a change meant to fix one flow did not regress another.
• Regulated call flows: Verify identity checks and escalation paths in healthcare, insurance, and financial services.
• High volume support lines: Find the intermittent failures that only surface across dozens of calls.
• Vendor evaluation: Grade a shortlisted voice agent vendor on the same behaviors your callers depend on.

If automating voice is still one option among several, the Business Automation Audit helps you decide what to automate first, and the AI Agent Readiness Quiz checks whether your team is set up to support one. This audit is maintained by TestMu AI (formerly LambdaTest), which runs testing infrastructure across 10,000+ real devices and 3000+ browsers.

Frequently Asked Questions (FAQs)

Is the AI voice agent audit really free?

Yes, the AI voice agent audit is free. There is no charge, no credit card, and no purchase obligation. You submit the request form, TestMu AI runs the simulated calls, and the report reaches your inbox at no cost, and nothing is billed if you decide not to continue.

What does this page actually do when I submit the form?

The page is a request form, not an in-browser analyzer. Submitting it sends your contact details, your agent's phone number, and your selected behaviors to the TestMu AI audit team, who schedule the calls and email the finished report back to you.

How many test calls will my voice agent receive?

Your voice agent receives 30 or more simulated calls for every behavior you select. Choosing all seven behaviors queues 210 or more calls. Calls run one at a time at normal conversation volume, so the audit never spikes your agent's traffic.

How long does the audit take from submission to report?

The audit report arrives within two business days of your submission. The simulated calls usually finish within one day, and the remaining time covers transcription, scoring each behavior against its rubric, and a human review pass over every failed call before the report is sent.

Do I need to share my voice agent's code, prompts, or API keys?

No code, prompts, or API keys are required. The audit is fully black box. TestMu AI needs only the phone number your agent answers on, a short description of what it does, and the behaviors you want tested. Everything else comes from the live calls.

Is the AI voice agent audit a load test?

No. Calls are placed one at a time at normal volume to measure conversation quality, not concurrency. If you need to know how your telephony stack behaves under parallel call pressure, that is a separate performance testing engagement rather than this audit.

Do I need authorization to submit a phone number for testing?

Yes. You must own the voice agent or have explicit permission for it to receive automated test calls, and the form's authorization checkbox records that confirmation. A single verification call is placed before the full run to confirm the number reaches the agent you described.

What happens to the call recordings and transcripts?

Recordings and transcripts are used only to score your audit and to illustrate failures in your report. They are shared with you, not published or reused as training data. Reply to the report email if you want the underlying recordings deleted after delivery.

Can the audit test voice agents in languages other than English?

Audit simulations run in English by default, covering a wide range of accents, speaking speeds, and speech patterns. If your voice agent serves callers in another language, note it in the agent description field and the audit team will confirm whether that language is supported.

Does the audit work for web based voice agents without a phone number?

The audit supports voice agents you can reach by dialing a phone number. Web only voice widgets, in-app assistants, and agents behind authenticated softphones are not covered. If your agent can be exposed on a temporary test number, the audit can run against that.
