Here's a CNBC article, but it's all over the news today.
Founded by Ray Kurzweil, a name familiar to many in the blind community, Nuance is a pioneer in OCR and speech recognition technology. It has produced the OmniPage OCR software and Dragon speech recognition software. Nuance partnered with Apple to produce the technology used in SIRI. Older members of the blind community will recall using Kurzweil OCR machines. Kurzweil is the K in the KNFB reader iOS app.
Microsoft will acquire Nuance for $16 billion. Does anyone know if Kurzweil still owns a controlling share of Nuance? If so, he's now a wealthy man.
