Hamming research

Our research methodology.

Hamming was first to market with a platform for testing voice agents. Every framework, benchmark, and recommendation we publish is grounded in production data from real voice agent deployments.

How we conduct
research.

Our research methodology combines automated analysis with expert validation.

  • Step 1

    Data collection

    We collect data from production voice agent deployments and synthetic test calls designed to stress-test edge cases.
    • Production call recordings from enterprise customers (anonymized)
    • Synthetic test calls simulating diverse user behaviors
    • A/B comparison data across voice platforms
    • Multi-language and multi-accent test scenarios
  • Step 2

    Analysis approach

    We combine automated LLM-as-judge scoring with manual expert review for nuanced failure analysis.
    • Automated scoring for consistency at scale
    • Manual expert review for edge cases and nuanced failures
    • Statistical validation across deployment segments
    • Regression detection between model versions
  • Step 3

    Quality standards

    All findings are validated across multiple deployments before publication.
    • Findings validated across 3+ enterprise deployments
    • Data anonymized and aggregated for privacy
    • Regular methodology review and iteration
    • Transparent disclosure of limitations
