Highest paying interpreter career specializations are part of the larger language interpreting industry. For many people, interpreting as a career is synonymous with translation. While both involve some form of communication from one language (source) to another (target), there are significant differences.
An interpreter’s job involves the spoken language only. While the translator has the luxury of using translation aides such as dictionaries and computer programs, an interpreter has to verbally translate what one person is saying in one language into a another language for another person to understand what the first said. In essence, an interpreter echoes what one person says but in another language.
