Two interpreters are required for simultaneous interpretation when a community meeting is expected to last more than two hours. Simultaneous interpretation demands sustained, high‑level cognitive processing, and interpreter accuracy declines without regular rotation. Using a team of two ensures interpreters can alternate, prevent mental fatigue, and maintain consistent, uninterrupted communication for all participants.
For board meetings, city council meetings, candidate forums, and webinars, two interpreters are requiered regardless of meeting length. These settings typically involve rapid exchanges, technical language, and high public visibility, all of which necessitate team interpreting to preserve quality and reliability.
