Language interpretation

language culture Maturity 7-9 Next article →

Language interpretation is the process of converting spoken or signed language into another language. This usually happens in real time to allow live communication between people. It is distinct from translation, which involves written texts. Translation is often more deliberative and allows for the use of external tools. Interpretation, however, requires immediate processing of the source language.

This skill is essential for diplomacy, law, and international cooperation.

There are two primary modes of interpretation: consecutive and simultaneous. In consecutive interpretation (CI), the interpreter waits for the speaker to pause before speaking.

This method can take up to double the time of the original speech. Interpreters may use short segments, which rely on memory, or long segments, which require intense note-taking. These notes must be clear and legible to maintain speed. Some interpreters also perform sight translation, which combines interpreting and translation for written documents.

Simultaneous interpretation (SI) occurs while the speaker is still talking.

This mode saves time and maintains the natural flow of the conversation. In a professional setting, the interpreter often sits in a sound-proof booth. They wear earphones to hear the speaker and a microphone to transmit their own voice.

A third, less common method is whispered interpretation, known as chuchotage. The interpreter speaks at a low volume to a few people nearby. This avoids disturbing others who are listening to the original language.

Interpretation is an ancient human activity that predates the invention of writing.

For much of history, it was not a major focus of academic study. Historians often focused on written texts rather than spoken words. Many interpreters were also treated as mere support staff rather than professionals. We learn about historical interpretation through letters, diaries, and memoirs. These documents often mention interpretation only incidentally. The English word "interpreter" comes from the Latin term for an explainer.

Modern technology revolutionized the field in the early 20th century.

In the 1920s and 1930s, Edward Filene and Alan Gordon Finlay developed equipment with IBM. This technology allowed for much more efficient large-scale communication. A major milestone occurred during the Nuremberg trials in 1945.

At these trials, simultaneous interpretation was used for French, Russian, German, and English. This success helped move the profession toward simultaneous methods.

The shift from consecutive to simultaneous interpretation changed international diplomacy. In the 19th century, most European diplomats spoke French fluently. This reduced the need for professional interpreters during discussions. After World War I, the need grew as leaders like Woodrow Wilson were not linguists. By 1951, the United Nations expanded to five working languages. These languages included English, French, Russian, Chinese, and Spanish. Because of this expansion, consecutive interpretation became impractical for large meetings.

Today, interpretation is divided into several specialized professional markets. Conference interpretation occurs at large meetings or international institutions. The International Association of Conference Interpreters (AIIC) represents over 2,800 professionals. These members work in more than 90 different countries. There is also judicial interpretation, which takes place in courts and legal settings.

This ensures that legal proceedings are understood by all parties involved. Interpretation remains a vital link in our globalized world.
