HIST 330 Deafness and Technology: CART and C-Print

This guide discusses some Deaf technologies that DHH people used in the past and use today.


Some Deaf people prefer to use CART or C-Print when participating in classes, workshops, or meetings. CART stands for Communication Access Realtime Translation, also referred to as realtime captioning or live-event captioning. CART transcribes the spoken word into English text verbatim using a stenotype machine, notebook computer, and realtime software. They type every spoken word, including false starts, misspeaks, and filler phrases. One hour of lecture will produce approximately 25 pages of transcript.The text appears on a computer monitor which the Deaf consumer reads. CART is also provided remotely via the Internet or telephone connection.

C-Print is a speech to text captioning technology and service developed by Dr. Michael Stinson at NTID, a college of RIT. This service is used in classes and other settings. It can also be used with those who are partially blind or have learning differences. A trained operator, a C-Print captionist, produces a text display of the spoken information and provides as much information as possible in grammatically correct written language. This system is called meaning-for-meaning service and will not include false starts and misspeaks. They use visual formatting such as bold, italics, and lists. One hour of lecture will produce approximately 15 pages of transcript.  The consumer reads the display and can access the text in paper or electronic format for notes. C-Print software uses a keyboard abbreviation system that is based on phonetics. Training is available and more information is available at this website. There is also  C-Print mobile software available which allows consumers to access information out of the classroom. C-print is also provided remotely via the Internet or telephone connection.
