There are two types of interpretations:

Consecutive Interpretation

Consecutive interpretation means interpreting what is said, after it is said. This mode of interpretation is used when the communication between the parties involves a two way exchange of information. It is ideal for question and answer settings, meetings and conversational formats, where communication is flowing in both directions, to and from the sources.

The message is heard in the source language; it is then carefully interpreted and delivered in the target language. The consecutive mode of interpretation is truly an exercise in memorization, as it requires a faithful and complete interpretation of the message being interpreted.

Simultaneous Interpretation

The simultaneous mode of interpretation involves the interpretation and rendering of the message from the source language to the target language instantaneously as it is heard by the speaker. In a sense, the interpreter is listening and speaking at the same time.

This mode of interpretation involves communication in one direction only, and it is often done continuously without pauses or interruptions.  This mode of interpretation is an exercise in language speed as the conversion process is done extremely fast.
