Simultaneous interpreting is a specialized form of communication in which the interpreter listens to the source language, and converts it to the target language almost concurrently. Although this form of interpretation does not always require transmission and receiver equipment it is often used for medium to larger groups. Interpreting in a smaller group setting does not diminish the complexity of this form of interpreting. This communication mode typically requires a team of professionals that display a mix of both self-confidence and ability. The interpreters must decipher the spoken sentence into the target language while simultaneously listening to and comprehending the next sentence. Not an easy task! That is why the team will take turns every 15 to 30 minutes depending on the complexity of the presentation.
