What types of interpreting services do we offer?

1 – Liaison interpreting services

As the name suggests, the liaison interpreter’s role is to act as a liaison between two parties that don’t speak the same language. The speaker(s) have to stop to give the interpreter time to translate the content of the conversation. This technique is commonly used at business or training meetings.

2 – Telephone interpreting services

The telephone interpreter provides interpreting by telephone. The idea is simple: The service provider sets up a telephone conference, for example, between two or more people who don’t speak the same language, and places a liaison interpreter between them who will translate the conversation bit by bit. The service is the same as liaison interpreting, except that the speakers are not physically present.

3 - Video remote interpreting services

Interpreting by video is a natural development of telephone interpreting, which only became possible with the widespread use of the Internet. Today, video conferences for two or more participants can be set up simply by clicking on the Internet using various programs and tools, some of which are free.
