The two most common types of interpreting are simultaneous interpreting and consecutive interpreting. In the case of consecutive interpreting, a speaker will utter one or more sentences while the interpreter takes notes. The speaker then pauses while the interpreter reproduces what the speaker has said in the other language, for the benefit of the audience or listening party. In the case of simultaneous interpreting, a speaker delivers a speech without any break, and the interpreter reproduces what the speaker has said in the other language in real time (in effect, simultaneously) for the audience or listening party.

The languages we offer include English, Japanese, French, Spanish, Russian, Chinese and Arabic.
