Apple’s AI-based Siri assistant to let you control app functions with voice

Apple Inc. is planning to overhaul its Siri virtual assistant with more advanced artificial intelligence, a move that will let users control individual app functions with their voice, according to people with knowledge of the matter.

The new system will allow Siri to take command of all the features within apps for the first time, said the people, who asked not to be identified because the initiative isn’t public. That change required a revamp of Siri’s underlying software using large language models — a core technology behind generative AI — and will be one of the highlights of Apple’s renewed push into AI, they said.
