    A whitepaper on architecting Voice AI systems enterprises can trust: accurate, auditable and safe by design. Why naïve RAG falls short, where production systems fail, and the framework for building beyond it.

    The whitepaper, at a glance

    Enterprises are deploying Voice AI at scale, but most architectures were not designed for the rigorous demands of regulated, high-stakes environments. RAG is a starting point, not a destination. This paper sets out the architecture and operational principles that move teams beyond it.

    • The challenge. Why enterprise Voice AI is failing at scale.
    • Why RAG isn't enough. Limitations of naïve retrieval architectures.
    • Failure points in Voice AI. Telephony, ASR, retrieval and LLM breakdowns.
    • Real-world data insights. What millions of voice interactions reveal.
    • Governance & compliance. Explainability, auditability and regulatory pressure.
    • Risks of poor architecture. Hallucinations, downtime and data exposure.
    • The solution framework. Governed knowledge, hybrid retrieval, multi-agent design.
    • The reliable Voice AI stack. From observability to scalable architecture.

    Three numbers worth internalising

    3×
    More likely to deliver value

    Organisations with structured AI governance frameworks are 3× more likely to realise measurable business value from GenAI initiatives.

    50%
    Failures from telephony

    Half of all Voice AI production incidents originate from telephony or audio layers, not the LLM itself.

    96%
    Factual accuracy achieved

    Hybrid retrieval architectures combining vector, keyword and graph search achieve up to 96% factual correctness in financial Q&A tasks.

    The EU AI Act hits voice: what August 2026 means for conversational AI

    The Act's high-risk obligations apply from 2 August 2026. Most voice AI in production is limited risk, but emergency triage, recruitment, credit, insurance, education and public services are not. What actually applies to a voice agent, where the line falls by industry, and the role trap that turns a buyer into a provider.
