Robert Scoble reports that Apple has purchased Siri, a company that has developed a free personal assistant application for the iPhone and iPod touch. Selected as the Most Innovative Web Technology in a contest at this year's SXSW festival, Siri offers automated personal assistant services by integrating a rapidly growing number of third-party services such as OpenTable, FlightStats, and Google Maps with voice-recognition technology from Nuance Communications.
Scoble discovered evidence (PDF) of the deal through a notification given by the U.S. Federal Trade Commission announcing an early termination of the standard waiting period for corporate mergers to allow the transaction to proceed. Mashable and ReadWriteWeb are also confirming that they have heard about the acquisition from their sources.
Update: Silicon Alley Insider reports that a Siri representative has confirmed Apple's acquisition of the company.
Update 2: The Wall Street Journal quotes a Siri board member and investor as calling Apple's offer a "no-brainer".
"The offer from Apple was of a scope and tenor that it was a no-brainer to accept it," said Shawn Carolan, a managing director at Menlo Ventures and a board member at Sirti [sic] since it raised a Series A round of venture capital in 2008.
