Other failures come from expecting self-serve audio-to-text behavior when the real requirement is interpreter handoff continuity and media routing discipline for remote simultaneous interpretation.

  • Treating terminology control as a one-time glossary import instead of a live stability workflow

    Welocalize and RWS both depend on workflow configuration for consistent live output, so glossary setup must match the event’s live session structure and routing.

  • Skipping interpreter handoff design for continuous multi-segment conversations

    Day Translations and Lionbridge are built around handoff coordination, so live plans must define how handoffs occur between interpreters and how continuity is maintained across segments.

  • Assuming API-driven session routing works without engineering discipline for languages and roles

    PoliLingua flags that best results depend on disciplined setup of languages and roles, so governance over routing configuration must be part of the deployment plan.

  • Underestimating media routing and audio capture constraints that affect real time performance

    JR Language requires setup that matches audio routing and mic pickup quality for each room, so deployment scope must include on-site media constraints and validation.

  • Choosing an interpreter logistics workflow while needing enterprise integration visibility
