Apple's (AAPL) recently appointed head of engineering for Siri, Mike Rockwell, is overhauling the team leading the voice assistant's development with talent from the group that designed the Apple Vision Pro software, Bloomberg reported Tuesday, citing people with knowledge of the matter.

Rockwell is also reshuffling teams working on speech, comprehension, performance, and user experience, according to the people.

Rockwell appointed Ranjit Desai to lead the development of Siri's platform and systems group and Olivier Gutknecht to oversee the assistant's user experience, according to the report.

Bloomberg said the company's software engineering managers, Nate Begeman and Tom Duffy, will join the Siri team to revamp the assistant's architecture. Stuart Bowers, who has experience in training and evaluation teams, will work on Siri's user-response features, while David Winarsky will refine voice and speech-related aspects.

Upgrading Siri is among Apple's top challenges, and the company is working to redesign the technology to leverage a large language model-based system. According to Bloomberg, this could take several years to complete.

Apple didn't immediately respond to a comment request from MT Newswires.

Shares were up nearly 4% in recent trading.
