The Vice President (VP) of the Siri team at Apple -- Bill Stasior -- has reportedly stepped down from his designation after seven years of service.
The Information reported on Friday, "Though Stasior remains in the company, he is no longer heading the voice assistant group, said five people with knowledge of the change,"
Giannandrea's aim is to bring long-term research-based changes to Siri rather than just focusing on incremental improvements.
He is expected to also look for a new Siri leader.
Apple has not yet released an official statement confirming or declining the reports of Stasior's stepping down.
Announced as part of iPhone 4S, Siri came into existence as Apple's mainstream voice assistant in 2011.
