OpenBook™ converts printed documents or graphic-based text into an electronic text format on your PC, using quality speech and the latest optical character recognition (OCR) technology. Easy switching between the Nuance OmniPage® and ABBYY FineReader® OCR engines allows you to choose the OCR engine that works best for your particular use. You also can choose between two leading text-to-speech software synthesizers: RealSpeak™ Solo (natural, human-sounding voices) or Eloquence (efficient synthesized speech that often is preferred for editing and document skimming).
