How It Works: Sign Language Interpreter

By Tisha Vaughan


A type of communication that adopts visuals, such and manual communication and body movement, to communicate is called sign language. The job of a sign language interpreter is to translate audio messages into visual messages or vice versa. This form of communication relies heavily on shapes, movement and orientation of the body, specifically the arms and hands. It also uses facial expressions.

Interpreters must be competent in at least two languages, one being sign. Most of these individuals are formally trained and have a degree or certificate. Trained interpreters, when working in large settings, position themselves in an area where they can see both the deaf and hearing parties.

There are different ways that interpretation can be handled. On-site, or in-person, interpreting is the most conventional form. As its title suggests, this requires the physical presence of all parties involved.

The telephone is another technology utilized for this work. This type of communication is called telephonic or over-the-phone. Typically it involves a conference call and is done when on-site interpreting is unavailable.

Another option is video interpreting. This method involves the use of video relay systems, or video remote interpreting. It is especially useful when one or more of the participants are deaf, hard of hearing or speech impaired. Through real-time audio and video feeds, the interpreter can see and communicate with all parties involved in the interaction.

Overall, signing is used in a variety of occasions and settings. It may be used in places where speech is not allowed or practical. For instance: baseball, hunting, underwater, loud workplaces or recording studios. In recent years, parents have begun teaching their toddlers signing before the children can effectively communicate through speech. In cases where there are impaired parties, full-time interpreters are on call. Many of these individuals work full time in places such as health care facilities, phone interpreting agencies, schools, government agencies, courts and the military.
