| Simulation of Scenarios | Create varied conversation flows: prompts, transcripts, audio, voice, with different environments and accents. Edge cases, interruptions, etc. coval.dev+2coval.dev+2 |
| Voice & Chat Compatibility | Use both text-based chat agents and voice agents (voice inputs, custom voices) in tests. Integration with voice simulation (including work with partners like Rime for realistic voices). coval.dev+1 |
| Built-in + Custom Metrics | Standard metrics (latency, accuracy, tool-call correctness, instruction compliance), plus custom metrics as per team’s needs. coval.dev+1 |
| Regression Tracking & Monitoring | Track performance over time, compare different versions of agents, alert when performance drops. Helps catch regressions early. coval.dev+2coval.dev+2 |
| CI/CD Integration | Coval can be integrated in development workflows so that every change is evaluated via simulation before deployment. Y Combinator+1 |
| Real-World Voice Edge Case Testing | Use realistic voice scenarios—accents, background noise, interruptions, real speech variations. Useful for voice assistants, phone IVRs, etc. coval.dev+2 |
