Nuance is an American based multinational computer software technology corporation, headquartered in Burlington, Massachusetts, United States on the outskirts of Boston, that provides speech and imaging applications. Current business products focus on server and embedded speech recognition, telephone call steering systems, automated telephone directory services, medical transcription software and systems, optical character recognition software, and desktop imaging software. The company also maintains a small division which does software and system development for military and government agencies. Nuance merged with its competitor in the commercial large-scale speech application business, ScanSoft, in October 2005. ScanSoft was a Xerox spin-off that was bought in 1999 by Visioneer, a hardware and software scanner company, which adopted ScanSoft as the new merged company name. The original ScanSoft had its roots in Kurzweil Computer Products, a software company that developed the first omni-font character recognition system.
