A stenograph machine is a chorded keyboard that only has 22 keys. Instead of typing letter by letter like on a QWERTY keyboard, Caption Pros captioners use machine shorthand to “write” phonetically.
Much like playing a musical instrument, captioners press specific combinations of keys to represent sounds or syllables. These key combinations are translated against a database in specialized software to create English words. With the help of stenographs and software, captioners can deliver real-time captioning with 99%-plus accuracy.
