The main mover and shaker behind the iPhone 4S’s headline-grabbing Siri voice control app has left Apple, a matter of weeks after the service was unveiled at the handset's launch.
Siri, whose application enables users to control an iPhone 4S handset using only their voice, was acquired by Apple last year for an outlay thought to be in the region of around $200 million.
According to All Things D, Dag Kittlaus, founder and CEO of Siri, has left the Cupertino giant just over 18 months after the deal was completed, reportedly to spend more time with his family and work on other projects.
His departure is thought to be unrelated to problems with the app, which purportedly include handset's connection dropping out while Siri is in use, that have prompted much sniping from tech watchers.
Touted as the iPhone 4S’s killer application, Siri users can use voice commands to carry out web searches, schedule appointments and dictate emails and texts.
