At-scale automated testing
& production monitoring
for voice and chat agents

We evaluate holistically. Did the caller's goal get accomplished? That's what matters—not whether each turn matched a script exactly.

Conversations take many paths. Turn-by-turn matching is brittle and breaks constantly. We use AI to understand intent and outcomes.

We support 65+ languages including English, Spanish, Portuguese, French, German, Arabic, Hindi, Tamil, Japanese, Korean, Mandarin, and more.

Regional accents matter. We support South Indian, Gulf Arabic, UK English, Australian, Latin American Spanish dialects, and many more.

Yes. We simulate realistic caller behavior including interruptions, barging in mid-sentence, long silences, and unexpected inputs.

We also simulate background noise, elderly callers, fast/slow speakers, and emotional conversations—the real-world scenarios your agents will face.

Hamming is the only complete platform for voice agent QA—combining every capability other platforms specialize in, plus features they don't have:

• Automated scenario generation (pioneered by Hamming) — AI-generated test cases from your agent's prompts and documentation
• Audio-native evals — Analyze audio directly, not just transcripts. 95-96% agreement with human evaluators
• Production call replay (Scenario Rerun) — Replay real calls against new agent versions with one click
• 1,000+ concurrent call stress testing — With realistic voice characters, accents, and background noise
• Compliance validation — SOC 2 Type II, HIPAA with BAA, audit logs exportable to your SIEM
• Security red-teaming — Prompt injection, jailbreak, and PII leakage testing
• Enterprise controls — RBAC, SSO, single-tenant deployment, data residency (US/EU/UK)
• CI/CD integration — Trigger tests on every PR, gate releases on pass rates

With a 90% win rate in head-to-head bake-offs, Hamming is the proven choice. If you're evaluating Hamming against another platform, ask them how they're different from Hamming.

We measure voice agent quality across three dimensions: conversational metrics, expected outcomes, and compliance guardrails.

Conversational metrics include turn-taking latency, interruptions, time to first word, talk-to-listen ratio, and more—tracked across both tests and production calls.

Expected outcomes let you define what success looks like for each call: did the agent collect the required information, complete the booking, or resolve the customer's issue?

Compliance guardrails catch safety violations, prompt injection attempts, and policy breaches—so you can audit every call against your rules.

Hamming maintains SOC 2 Type II compliance and supports HIPAA.

For healthcare deployments, we can sign a Business Associate Agreement (BAA).

We can generate 1K+ calls / minute for inbound, outbound, or direct WebRTC—so you can stress-test latency, handoffs, and edge cases before customers do.

Every few minutes we replay a golden set of calls to detect drift or outages (model changes, infra incidents, prompt regressions).

We send email and Slack alerts when we detect issues—so you catch problems before your customers do.

Yes. We emulate IVR menus, send DTMF tones, and test both inbound and outbound agent flows end-to-end.

Yes. When a production call fails or surfaces an issue, convert it to a regression test with one click. The original audio, timing, and caller behavior are preserved—you test against real customer conversations, not synthetic approximations.

This production call replay capability ensures your fixes work against the exact conditions that caused the original failure.

Yes. Define custom evaluators for your business rules—compliance scripts, accuracy thresholds, sentiment targets, domain-specific criteria. Score every call on what matters to your business, not just generic metrics.

Hamming includes 50+ built-in metrics (latency, hallucinations, sentiment, compliance, repetition, and more) plus unlimited custom scorers you define.

Paste your agent's system prompt. We analyze it and automatically generate hundreds of test scenarios—happy paths, edge cases, adversarial inputs, accent variations, background noise conditions.

No manual test case writing required. Hamming pioneered automated scenario generation for voice agents—other tools are still catching up.

Yes. Hamming natively ingests OpenTelemetry traces, spans, and logs. Get unified voice agent observability—testing, production monitoring, and debugging—in one platform.

Hamming complements Datadog and your existing observability stack. The value is keeping all core voice agent data—test results, production calls, traces, evaluations—unified in one place for faster debugging and deeper insights.

Yes. Hamming's speech-level analysis detects caller frustration, sentiment shifts, emotional cues, pauses, interruptions, and tone changes. We evaluate how callers said things, not just what they said.

This goes beyond transcript-only tools that miss crucial vocal signals. Audio-native evaluation catches issues that text analysis cannot.

Yes. Hamming tests both voice and chat agents with unified evaluation, metrics, and production monitoring. Whether your agent speaks or types, you get the same comprehensive QA platform—one set of test scenarios, one dashboard, one evaluation framework.

This multi-modal capability means teams building conversational AI don't need separate tools for voice and chat. Auto-generate scenarios, define assertions, run regression tests, and monitor production—all in one platform regardless of modality.

Teams switching from developer-focused alternatives to Hamming cite faster time-to-value, less configuration overhead, and more consistent evaluation. While some platforms require weeks of configuration before running your first test, Hamming gets you testing in under 10 minutes.

The key difference is evaluation consistency: Hamming achieves 95-96% agreement with human evaluators by using higher-quality models and a two-step evaluation pipeline. Platforms that use cheaper LLM models often produce inconsistent pass/fail reasoning that engineers can't trust.

Developer-first doesn't mean developer-only. Hamming delivers engineering rigor (full REST API, CI/CD native, webhooks) with cross-functional accessibility (dashboard, reports, audio playback) so your whole team can collaborate on agent quality.

Yes. We offer startup and SMB-specific pricing designed to match your usage. Early-stage startups get pricing that scales with their team, while enterprise customers get custom plans with dedicated support and compliance features.

Hamming serves startups and enterprises equally well. YC-backed startups run their first tests in under 10 minutes after a quick onboarding call. Enterprise teams get the same speed with additional compliance (SOC 2, HIPAA), dedicated support, and custom SLAs.

Unlike point solutions that force you to outgrow them, Hamming scales from day one. Start with 10 test cases, scale to 10,000. Add enterprise support when you need it. The platform grows with your team.

Many of our startup customers started testing the week they launched their voice agent and stayed with Hamming as they raised Series A, B, and beyond. No migration required.
