In simultaneous interpreting, the interpreter immediately speaks the message in the target-language whilst listening to it in the source language.

In consecutive interpreting, the interpreter renders the source-language message after the source-language speaker pauses.

Conference interpreting is interpreting in a conference environment. And it can be either simultaneous or consecutive.

Legal/court interpreting takes place in courts of justice or administrative tribunals and wherever a legal proceeding is held (such as a conference room for a deposition or the location of a sworn statement). Legal interpreting can take the form of consecutive interpreting of witnesses' statements, for example, or simultaneous interpreting of the entire proceedings by electronic means for one or more of the people in attendance.

Escort interpreting is when an interpreter accompanies a person or a delegation on a tour, or on a visit, or to a meeting or interview.

American Sign Language Interpreting (ASL) provide effective communication access for the deaf and hard-of-hearing.
