Our FAQ section provides answers to common questions about Sign Language Interpreting (SLI) and Communication Access Realtime Translation (CART) services. It covers when and how to request these services, the types of events where they are recommended, and essential technical considerations. You’ll also find helpful tips on working with interpreters and captioners to ensure smooth communication and accurate service.
Understanding SLI & CART Services
- What is a Sign Language Interpreter (SLI)?
A Sign Language Interpreter (SLI) is a trained professional who interprets spoken language into a manual language, and vice versa, allowing hearing, Deaf, Deaf-Blind, and hard of hearing individuals equal access to information and interactions.
- What is Communication Access Realtime Translation (CART)?
Communication Access Realtime Translation (CART), also known as real-time or live captioning, provides instant translation of spoken words into text. The text can be displayed on an individual’s device, projected onto a screen, or combined with a video presentation as captions. CART services can be provided remotely or in-person, depending on the event’s needs and availability.
- When should I use SLI or CART for meetings/events?
It is recommended to provide SLI and/or CART services at any event where an elected official or a City Department representative will be speaking on camera or to the general public. Auxiliary aids and services are required for emergency communications, such as press conferences or media briefings. If possible, consider using remote services (SLI or CART) to increase the likelihood of fulfilling the request, as in-person availability is limited.
- When should I submit an SLI or CART request?
Requests should be submitted at least five (5) business days before the event. While the Department on Disability will do its best to accommodate requests with shorter notice, securing last-minute interpreters or captioners may not always be feasible.
- How many interpreters will attend the meeting/event?
For panel discussions, sessions with more than two people, or large events, two (2) or more interpreters may be assigned.
- What if I need to cancel an SLI or CART request?
Cancellations must be made at least 48 hours before the event or activity for which SLI or CART services were requested. Please email sli.cart@lacity.org.
- What equipment is needed to provide CART?
For remote CART services, the hosting department must provide a video conferencing platform link, such as Zoom or Google Meet. For on-site CART, the hosting department must provide a screen or monitor and the necessary equipment (Wi-Fi credentials, HDMI cable, etc.) to display the captions. The department is also responsible for ensuring that the captioner can clearly hear the speakers.
Technical Considerations
- Audio
Captioners need access to clear, reliable audio from your event. Audio options include:
- Wearable wireless microphone for the speaker or presenter
- Desktop microphone
- Headphones
- Speakers
- Room array microphone
- Tablet or smartphone with a microphone
- If a speaker system is already in place, test the placement of the tablet or microphone in front of the loudspeaker.
- Internet Bandwidth
A strong, stable internet connection is required to transmit the audio signal to the captioner and the captions back to the audience. StreamText "captions only" requires about 500 bytes per second, while adding audio transmission requires approximately 500 Kbps. Requirements increase if video is included (e.g., Zoom).
- Stable Environment
Ensure the CART provider has a stable surface and access to electricity during the event.
- Caption Streaming
Live captions are streamed over the internet to the CART user’s smartphone, tablet, or laptop. StreamText.net is an industry leader in real-time text accessibility and provides excellent service and support. The CART user receives a URL that opens StreamText in a standard browser. Text color, background color, and font size can be customized based on the user’s preferences.
