Siri Co-Founder Kittlaus Departs From Apple

Dag Kittlaus — the co-founder and CEO of the company that created the Siri voice control feature, which Apple launched to much acclaim recently — has left the company, according to sources.

There were several reasons for the departure, which was amicable and has been planned for a while, sources said. They included Kittlaus’s family being in Chicago, a desire to take time off and an interest in brainstorming new entrepreneurial ideas.

Kittlaus has led the speech recognition efforts for Apple since Apple bought Siri in April of 2010. He had been Siri’s CEO since 2007. Before that, the Norwegian-born Kittlaus was an Entrepreneur in Residence at the Stanford Research Institute and had also worked at Motorola.

Kittlaus apparently left just after the launch of the iPhone 4S, in which Siri’s speech recognition technology was the highlight, but sources said other key execs from Siri are expected to remain at Apple.

I have queried Apple PR and am waiting for a response.
