What is NOT one of the four common communication barriers in interpreting?

The correct answer is identified as audience misunderstanding, which is not one of the four common communication barriers specifically addressed in the context of interpreting. The four primary barriers usually include linguistic challenges, role confusion, service system barriers, and cultural differences.

While audience misunderstanding can certainly occur in communication, it doesn't directly stem from the interpreter's work but rather from the circumstances surrounding the communication event. The other options relate directly to the roles and responsibilities of interpreters and the dynamics within interpretation scenarios.

Linguistic challenges refer to the difficulties that arise from language differences, while role confusion pertains to the interpreter's understanding of their role versus those of the participants. Service system barriers involve the structural aspects that may hinder effective communication, such as administrative issues or lack of access to interpreting services. By focusing on these specific barriers, we can ensure effective communication in interpreting settings.
