Abstract: A system configured to provide a transcription building interface may be usable by transcribers to produce versions of textbooks and other works in accessible formats such as braille. The interface may receive data from a publisher of a work, such as a NIMAS file set, which provides a starting point for transcription but must be further modified to produce a production ready braille version. The interface presents a print display, a braille display, and a style display of the underlying data, and may receive input modifying the content of one or more of those displays, with any changes synchronized across each. The interface further provides toolsets that may be used to automate the creation of certain complex content in braille, including tools for describing lists, mathematical concepts, and images, which have conventionally been manually encoded.
