On-site vs. Remote Simultaneous Interpreting: Equipment and Logistics

Equipment and Logistics in Simultaneous Interpreting: A Comparison Between On-site and Remote Settings

18 August 2025, Bangkok – Simultaneous interpreting (SI) is an essential communication tool in international conferences, whether in diplomacy, business, or intergovernmental organizations. The choice between on-site simultaneous interpreting (OSI) and remote simultaneous interpreting (RSI) depends not only on interpreter availability but also on the equipment and logistics required, which significantly affect overall costs and service quality (AIIC, 2021; ISO, 2016, 2017, 2022).

On-site Simultaneous Interpreting (OSI)
Required Equipment
On-site interpreting relies on standardized equipment, including:

• Soundproof interpreter booths
• Interpreter consoles
• Microphones and headsets for delegates
• A technician for sound system support

Budget Implications
The costs of OSI extend beyond interpreter fees and typically include:

• Rental and transportation of booths and consoles
• Setup and dismantling fees
• Technician service fees

In many cases, logistical and equipment-related costs may exceed interpreter fees, substantially increasing the overall budget (Donovan, 2017).

Remote Simultaneous Interpreting (RSI)
Required Equipment

RSI is based on digital platforms with interpreter functions such as Zoom Interpreter Mode, Kudo, or Interprefy. Interpreters require:

• A computer with high-quality headsets
• Stable, high-speed internet
• A quiet, professional working environment

Budget Implications
RSI reduces the need for large-scale rental and onsite setup. While it introduces new costs, such as:

• Platform licensing fees
• Technical support for online operation
• Overall budgets are generally lower than for OSI, even when interpreter daily rates remain similar (Moser-Mercer, 2018).

Comparison of OSI and RSI

Conclusion
Both OSI and RSI offer unique advantages and limitations. OSI ensures high-quality sound and formal reliability but comes with significant logistical and equipment-related expenses. In contrast, RSI reduces costs and enhances flexibility, though it presents risks related to connectivity and digital infrastructure. Choosing between the two modes requires considering not only interpreter fees but also the overall budget, event context, and the technical standards that can be ensured.
