History
Dr. James Baker laid out the description of a speech understanding system called DRAGON in 1975. Then in 1982 he and Dr. Janet Baker, his wife, founded Dragon Systems to release products centered around their voice recognition prototype. He was President of the company and she was CEO.
DragonDictate was first released for DOS, and utilized hidden Markov models, a probabilistic method for temporal pattern recognition. At the time, the hardware was insufficiently powerful to address the problem of word segmentation, and DragonDictate was unable to determine the boundaries of words during continuous speech input. Users were forced to pronounce one word at a time, each clearly separated by a small pause. DragonDictate was based on a trigram model, and is known as a discrete utterance speech recognition engine.
Dragon Systems released NaturallySpeaking 1.0 as their first continuous dictation product in 1997.
The company was then purchased in June 2000 by Lernout & Hauspie, a Belgium-based corporation that had been involved in financial scandals. Following the all-share deal advised by Goldman Sachs, Lernout & Hauspie declared bankruptcy in November 2000. The Bakers had received hundreds of millions in stock, but were only able to sell a few million dollars worth before the stock lost all its value as a result of the accounting fraud. The Bakers sued Goldman Sachs for negligence, intentional misrepresentation and breach of fiduciary duty, which eventually (January, 2013) led to a 23-day trial in Boston. The jury ruled in favor of Goldman Sachs and cleared Goldman Sachs of all charges. Following the bankruptcy of Lernout & Hauspie, the rights to the Dragon product line were acquired by ScanSoft of Burlington, Massachusetts. In 2005, ScanSoft launched a de facto acquisition of Nuance Communications, and rebranded itself as Nuance.
From 2012, LG Smart TVs include voice recognition feature powered by the same speech engine as Dragon NaturallySpeaking.
