Record completeness
Claims
no system simultaneously exceeds 0.5 on both EVA-A pass@1 and EVA-X pass@1; peak and reliable performance diverge substantially (median pass@k - pass^k gap of 0.44 on EVA-A); accent and noise perturbations expose substantial robustness gaps
That bot-to-bot simulated conversations with automatic validation sufficiently capture the distribution of real human voice interactions and that the composite metrics EVA-A and EVA-X align with downstream user satisfaction or task success in production.
EVA-Bench introduces a simulation-plus-scoring framework for voice agents that reveals no tested system exceeds 0.5 on both accuracy and experience metrics at pass@1.
