Interpretation is the act of explaining, reframing, or otherwise showing your own understanding of something. A person who translates one language into another is called an interpreter because they are explaining what a person is saying to someone who doesn't understand. That means you first need to listen and understand it properly and then interpret the information to others in their language, the language in which they can easily understand it.
Interpreting, is fundamentally the art of paraphrasing—the interpreter listens to a speaker in one language, grasps the content of what is being said, and then paraphrases his or her understanding of the meaning using the tools of the target language. An interpreter must be able to translate verbally on the spot, without using dictionaries or other supplemental reference materials.
Interpretation requires you to first understand the piece of music, text, language, or idea, and then give your explanation of it. A computer may produce masses of data, but it will require your interpretation of the data for people to understand it.
As the companies are trying to expand and enter into other territories and different countries and cultures, an interpretation service allows and helps them to interact with their target audience easily without the hurdles of language, as whatever you want to communicate and convey to your target audience, it can be easily interpreted and communicated.
Interpreting services are needed in almost all the fields such as medical, legal matters, travel industry, government offices, media, and advertising and many more.
