Interpreters help people who speak two different languages communicate. They must be fluent in the two target languages. Unlike translators, interpreters only provide spoken interactions, not written documentation. There are two forms of interpreting-simultaneous and consecutive. Simultaneous interpreting is when you listen and translate immediately, while the speaker is talking. This kind of interpreter is usually needed at large conferences or diplomatic meetings. Consecutive interpreting is best for face-to-face speeches or testimonies in court, where the speaker will say a few lines, then pause to give the interpreter a chance to relay their message in the second language. Individuals with severe speech or hearing impairments rely on sign language to communicate, so American Sign Language (ASL) interpreters help to convey the tone and message of the original communicator.
