Dag Kittlaus, CEO and co-founder of Siri, the voice control technology that dominated the iPhone 4S launch, has left Apple.
Siri along with the team that helped build it were bought by Apple in 2010, with the voice-activated personal assistant since becoming the headline feature of the iPhone 4S. Dag Kittlaus has now left the company in what has been described as an “amicable” and long-planned split by AllThingsDigital.
Kittlaus is now expected to pursue other entrepreneurial ideas, as well as spending more time with his family.
Kittlaus founded Siri alongside Adam Cheyer and Tom Gruber, with backing from Norman Winarsky. The remaining members of the Siri team are expected to stay on with Apple and help further develop the product.
Both Apple and rival mobile OS maker Google see a big future in voice control technology, each now offering increasingly advanced voice control features in their devices.
