How do I generate test scenarios for an AI voice agent?

Start with the agent's instructions and knowledge base. Our free generator analyzes both, identifies every objective the agent must handle, and produces a complete scenario set with defined objectives and success conditions — ready to run.

How many test scenarios does my voice agent need?

The exact count depends on your agent's instructions, intents, and knowledge depth. Most teams under-test with 10–30 scenarios. Our generator calculates the precise number required for complete coverage — so you test every objective once, and nothing twice.

Why aren't LLM-generated test scenarios enough?

Direct LLM generation produces different results every time — varying counts, blended intents, and open-ended conversations that drift. That's sampling, not testing. Reliable scenarios must be deterministic, focused on one objective, and closed with clear success conditions.

Is this AI voice agent scenario generator really free?

Yes. Generating scenarios is completely free — no credit card, no signup. Paste your agent's instructions, generate a full set, and download as CSV. To run scenarios at scale across human behavior profiles, use the full Evalgent platform.

What do I do with the scenarios after I generate them?

Export as CSV and run them in your test framework — or import to Evalgent to evaluate your agent against realistic human behavior like interruptions, accents, and noise. Measure reliability across hundreds of runs before users see failures.

Appointment booking

Customer calls to book a new appointment slot

Description

You signed up for a service online but never booked your first appointment because the process felt unclear. The provider has just called to help you get started. You're open to booking, but want to understand the process before committing. Follow these steps: 1. When asked if you'd like to book, say you're not sure how long the appointment takes. 2. Listen to how the agent explains the process. 3. Ask whether you can reschedule later if needed. 4. Once your questions are answered, share your availability and agree on a date and time. 5. Confirm the slot, get a reference number, and check that a confirmation will be sent.
