This unit describes the performance outcomes, skills and knowledge required to interpret from a source language to a target language in complex dialogue settings, preserving the communicative intent of the source language. It includes the ability to use a range of techniques to assist in the message transfer process and to address problems in delivery.An interpreter in the dialogue setting is required to interpret between two languages in both directions.Complex settings are those that may involve specialised subjects requiring a high level of subject knowledge, or intense assignment specific preparation. The elements of the setting, or the number of parties involved, may limit the interpreter from managing the interaction. In the complex dialogue setting, the interpreter may be required to switch modes in a challenging environment, where there is a range of participant interests and personal welfare and safety issues that need to be considered.Interpreting in this setting typically requires high levels of accuracy and accountability and assignments involving formality, or participants with high status and accountability. The content of communication may not easily be predicted or planned for, and there are limited opportunities for error correction. The consequences of errors in communicative intent can have significant implications.This unit applies to those working as interpreters in consecutive and simultaneous (in the case of signed language to spoken and vice versa) modes, either alone, or collaboratively as part of a team.The skills in this unit must be applied in accordance with Commonwealth and State or Territory legislation, Australian Standards and industry codes of practice.No occupational licensing, certification or specific legislative requirements apply to this unit at the time of publication.
