Simulate the callers your agent will actually face
Define tester agents with 8 behavioral parameters — from response delays and background noise to speaking pace and accents. Replicate the exact behavior of your audience so your agent is tested against the callers it will serve.

Fast-paced caller in a noisy environment
What is a voice agent tester profile?
A tester profile is a simulated caller persona used to evaluate AI voice agents. It defines 8 behavioral parameters — from response latency and background noise to speaking pace and accent.
Each profile replicates the exact callers your voice agent will face in production. Instead of testing against ideal conditions, you stress-test across real-world caller diversity.
Ship knowing exactly how your agent performs under pressure.
How do we ensure caller diversity?
Real-world network & environment diversity
Test how your agent handles the environmental challenges your real callers face — from unstable connections to noisy surroundings.
Behavioural diversity across callers
Replicate how your audience actually behaves on calls — their patience, interruptions, and speaking speed.
Demographic & voice diversity
Match the demographics and voice characteristics of the people your agent will actually serve.
Stress test one parameter at a time
Lock all parameters to a baseline, then vary a single one across its severity levels. Discover exactly where your agent's performance starts to degrade — and where it breaks entirely.

What are you missing?
Without profiles
- Same calm, cooperative tester every time
- No background noise variation
- Single accent and speech pace
- Failures only found in production
With Evalgent profiles
- Callers match your real audience demographics
- Noise, interruptions, and pace vary per test
- Behavioral edge cases tested before launch
- Breaking points identified systematically
