Our voice agent passed every test and still woke me up at 3am
Testing voice agents with real call transcripts can create a false sense of security, as it fails to capture rare or novel user behaviors. A developer experienced a critical failure when a caller switched languages mid-sentence, a pattern absent from their extensive test set of past production calls. To address this, the team shifted to simulating adversarial caller profiles, finding that while various tools can execute these simulations, the effectiveness hinges on well-defined personas rather than the specific testing platform.
