Crab it records the users even when they do not realize that they can have their conversations or actions recorded, they being sent for analysis to the company's partners. Apple claims that less than 1% of people's interactions with Siri are analyzed, but with billions of commands given daily, this number is extremely high.
According to one of Apple's partners who listened to and analyzed recordings from Siri, the assistant records people in a variety of situations. He says he heard people having sex, talking to the doctor, making deals, committing crimes, the recordings having the person's contact information attached, the recording location, and not only that.
Siri has recordings listened to by Apple's partners, just as Amazon Alexa or Google Assistant have recordings also analyzed by people. Everything is done so that the systems are improved, and Apple implies that everything the former employee of its partner company said, without referring specifically to the statements.
Considering that other companies have the personal assistants' recordings analyzed by third parties, if you think that Apple does not do this, it means that you have already been fooled.
"There have been countless cases of recordings that include private conversations between doctors and patients, business transactions, apparent crimes, sexual acts and so on. These records are accompanied by user data showing location, contact details and application data. Apple says: A small fraction of Siri requests are analyzed to improve Siri and dictation. User requests are not associated with the user's Apple ID. Responses provided by Siri are analyzed in secure locations and all employees are required to comply with Apple's strict privacy requirements."
