In an interview with NPR on Saturday, Barbra Streisand said Siri, the iPhone's digital assistant, doesn't pronounce her name correctly. So, she called Apple CEO Tim Cook.

Streisand said her last name is incorrectly pronounced with a "z" sound on the second "s."

Her request to change Siri's pronunciation of her last name was positively accepted.

Cook reportedly agreed to fix the pronunciation in time for the next iOS update, which Streisand said is set to be released "on Sept. 30."

That detail is another important point from the interview. Streisand may have leaked the release date for the next iOS update, which, if true, will come about two weeks after the expected release of the iPhone 7.
