These print-to-speech reading systems display the full image of documents, and can read the print aloud while highlighting what is being read.
Grader A: hit
Print-to-speech systems with page display and synchronized highlighting existed in 2009: the KNFB Reader Mobile (February 2008) showed captured text on screen with the spoken text highlighted, and Kurzweil 3000 provided reading support from scanned pages for students with learning differences.
Test: Feature test on the product class: shipping print-to-speech readers display the text and highlight words as read (KNFB Reader Mobile 2008, Kurzweil 3000). The claim describes how these systems work, not their spread.
Grader B: hit
Reading systems such as Kurzweil 3000 displayed the scanned page image and read text aloud with synchronized highlighting; this was already true before 2009.
Test: Capability test: shipping products by 2009.
