Definition & Overview
ISO 20108:2017 establishes the technical requirements for spoken language and sign language audio and video transmissions in remote interpreting environments. ISO 20109:2016 specifies the physical and ergonomic equipment standards for interpreting consoles, headsets, and monitoring systems used during simultaneous interpretation.
Key Technical Benchmarks
- Audio Frequency Range: Full 125 Hz to 15,000 Hz acoustic bandwidth for spoken language fidelity without compression artifacts.
- Lip-Sync Latency: Audio-to-video synchronization must remain within -20 ms to +40 ms to prevent severe cognitive fatigue.
- Acoustic Limiting: Compulsory inline peak limiting to prevent sudden acoustic trauma spikes exceeding 85 dBA.
- High-Definition Video: Clear view of the speaker's face, facial expressions, and presentation slides at ≥ 1080p 30 fps.
In Cabine: Cabine's audio rider generator enforces ISO 20108 acoustic frequency criteria and verifies venue streaming bitrates before dispatching remote or hybrid interpreter teams.
