Communication Access Realtime Translation — CART — is a service in which a trained captionist uses specialized equipment to transcribe spoken content into verbatim text, displayed on a screen, monitor, laptop, or personal device as it is spoken. There is no delay, no summarization, and no paraphrasing. Every word is captured as it is said.

CART is the access method of choice for many Deaf and hard-of-hearing individuals who are oral communicators, late-deafened adults, cochlear implant users, and others who prefer text-based access over sign language interpreting. It is also widely used alongside ASL interpreting in complex settings — legal proceedings, academic lectures, and large events — where a second channel of access improves comprehension.

For organizations, CART is a documented compliance solution under the Americans with Disabilities Act, Section 504, Section 508, and IDEA. Providing CART when requested is not discretionary in most institutional contexts — it is a legal obligation.

CART is not exclusively for individuals who do not know ASL. The population of Deaf and hard-of-hearing people who use or prefer CART is broader and more varied than many organizations assume.

Late-deafened adults — individuals who lost their hearing after acquiring spoken language — typically communicate orally and read English fluently. ASL interpreting may not serve them effectively. CART provides direct access to spoken content in their primary language.

Cochlear implant users — particularly in noisy or acoustically complex environments — benefit from CART as a supplemental or primary access channel.

Hard-of-hearing individuals — who can hear some but not all spoken content — use CART to fill the gaps that hearing aids and assistive listening systems leave, particularly in meetings, classrooms, and formal proceedings.

Individuals who use both ASL and CART — in complex settings such as depositions, medical consultations, or university lectures, some Deaf individuals prefer to have both an ASL interpreter and a CART provider simultaneously. The two services complement rather than duplicate each other.

Individuals with auditory processing disorders — who may have typical audiological profiles but struggle to process spoken language accurately in real time — often find CART provides clarity that no other accommodation does.

This question comes up consistently in legal, education, and healthcare contexts: can an organization satisfy its ADA or Section 504 obligation by turning on the automatic captions built into Zoom or Teams?

The answer, in almost all formal or high-stakes settings, is no.

Automated captions are generated by speech recognition algorithms. They are not verbatim, not consistently accurate, and not designed for the acoustic conditions of a deposition room, a school gymnasium, or a clinical consultation. They fail on proper nouns, technical and legal terminology, multiple simultaneous speakers, non-native accents, and any audio input that deviates from a clean single-speaker recording.

The ADA requires effective communication — not approximate communication. In a legal proceeding where accuracy is material, a medical setting where a patient is making informed consent decisions, or an educational assessment where a student’s performance is being evaluated, automated captions do not meet that standard.

CART, provided by a trained professional captionist, is the documented standard for communication access in these settings. It is what the law contemplates and what courts, school districts, and healthcare systems recognize as compliance.

Americans with Disabilities Act — Titles II and III Government entities and places of public accommodation must provide effective communication access on request. For a Deaf or hard-of-hearing individual who requests CART, declining to provide it in favor of a less accurate alternative is a compliance failure.

Section 504 of the Rehabilitation Act Federally funded organizations — including school districts, universities, and nonprofit organizations receiving federal funding — must ensure program access. Classroom CART for a student who requests it is a Section 504 accommodation obligation, not a discretionary decision.

Section 508 of the Workforce Rehabilitation Act Federal agencies and organizations procuring technology or information for federal use must ensure that communications are accessible. Live captioning of meetings and events falls within the scope of Section 508 for federal and federally connected organizations.

IDEA — Individuals with Disabilities Education Act Hard-of-hearing students in mainstream educational settings have the right to access instruction. CART is a documented and widely used accommodation in IEP and 504 plans for students who are hard of hearing or late-deafened.

California Education Code and Government Code California imposes additional accessibility obligations on state and local government entities and public schools beyond federal minimums. Organizations operating under state contracts carry corresponding compliance responsibilities.
