Test, Optimize and Deploy Voice AI with the world's leading companies
Real problems ML teams face with voice AI - and how we solve them. Based on patterns we see across hundreds of implementations.
70% of voice AI agents plateau at 80% accuracy after months of prompt engineering
— MIT Technology Review, 2024Our testing identifies which scenarios fail and why. Teams see 10-15% accuracy improvements within weeks.
4-7 minute average handle times are killing customer satisfaction scores
— Forrester ResearchOur optimization engine analyzes bottlenecks and reduces latency
Compliance requirements add 3-6 months to voice AI deployments
— Gartner Healthcare ReportPre-tested compliance templates for HIPAA, PCI, and SOC2. Cuts compliance overhead by 50%.
8-10% hallucination rates are destroying customer trust
— Stanford HAI StudySystematic testing helps identify and reduce common hallucination patterns. Teams typically improve by 40-60%.
30% of production issues come from untested edge cases
— Google Cloud DevOps ReportComprehensive testing finds 40-60 edge cases before production. 30% would have been critical failures.
65% of teams have no audit trail for prompt changes
— O'Reilly AI Adoption SurveyVersion control for prompts with A/B testing and instant rollback. Know what changed and revert in seconds.
