Sign language interpreting is a specialized form of interpreting that involves translating between a spoken language and a sign language or between two sign languages. This type of interpreting is particularly important for communicating with deaf and hard of hearing people, as they rely on visual signals such as gestures, facial expressions and body posture to understand information.

Sign language interpreters use a combination of hand gestures, facial expressions and body movements to convey the meaning of spoken words. Incidentally, sign language mainly uses facial expressions and body posture to express its grammar. This means that sign language speakers often look into each other's eyes instead of looking at their hands.

Simultaneous interpreting

The interpreter translates the speaker's spoken words into sign language in real time. The demands on concentration and reaction speed are correspondingly high here.

Consecutive interpreting

The interpreter waits until the speaker pauses after a few sentences and then translates the spoken text into sign language. This approach enables a more precise and detailed translation, but is more time-consuming as the speaker and interpreter take turns.

Sign language interpreters are essential in many sectors, including education, healthcare, the court system, the corporate world and cultural events. Their role is now also crucial at conferences, conventions and digital meetings to ensure accessibility and the full participation of deaf and hard of hearing people.

The integration of sign language interpreters in separate video channels is easily possible in video conferences and digital meetings, e.g. via Zoom or Microsoft Teams. Participants can open an additional, scalable window with the interpreters. This allows them to use the sign language support they need.

The use of sign language interpreters often requires the use of special conference technology:

• Lighting technology for sufficiently bright light so that the interpreters and signers are clearly visible to the audience.
• Video technology for digital transmission and recording of gestures.
• Microphones for the speakers so that the interpreters can clearly hear the sound they are supposed to interpret.
• Displays, screens or projectors so that the interpreters can interpret for everyone to see.

The exact technology depends on the type of event, the size of the room and the requirements.
