Simultaneous Interpretation (SI)

Simultaneous Interpretation


What is Simultaneous Interpretation?

  Simultaneous Interpretation (SI), sometimes erroneously called simultaneous translation, is a mode of interpreting in which the interpreter verbally translates what is being said into another language in real-time.

Simultaneous Interpretation vs Consecutive Interpretation


Consecutive interpretation (CI) is another mode of interpretation where interpreters await the speaker to deliver a few sentences before they start interpreting.

Simultaneous Interpretation is the most efficient interpreting mode. It allows you to communicate with your audience on the fly, instead of having to pause from time to time to wait for interpretation.


SI is applicable in meetings, conferences and events of all sorts and sizes, be it monolingual, multilingual, small, large, virtual, physical, casual or formal.


How does Simultaneous Interpretation work?

  To make Simultaneous Interpretation work, you will need the service of skilled interpreters together with SI technologies and equipment.





Due to the demanding and complex nature of SI, it is essential for interpreters to have the relevant educational background, language proficiency, expertise and extensive experience in SI.   


Work in teams


Depending on the duration, language and topic of the meeting, interpreters normally work in a team of two or three.

Simultaneous Interpretation Booth


As simultaneous interpretation requires deep concentration, interpreters need to work in sound-proof booths that isolate them from the participants.


Interpreters have a direct view of the conference room. This allows them to focus on both the voice and non-verbal cues of the speaker to deliver the most accurate interpretation.


Technical Support


A conference technician must be present and operate the SI system throughout the conference.
